Researchers at Chalmers University of Technology, Sweden, are now presenting a groundbreaking microscopy technique that allows proteins, DNA and other tiny biological particles to be studied in their natural state in a completely new way.</b></p>​<span style="background-color:initial">A great deal of time and money is required when developing medicines and vaccines. It is therefore crucial to be able to streamline the work by studying how, for example, individual proteins behave and interact with one another. The new microscopy method from Chalmers can enable the most promising candidates to be found at an earlier stage. The technique also has the potential for use in conducting research into the way cells communicate with one another by secreting molecules and other biological nanoparticles. These processes play an important role in our immune response, for example. </span><div><br /></div> <div style="font-size:16px"><strong>Revealing its silhouette </strong></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">Biomolecules are both small and elusive, but vital since they are the building blocks of everything living. In order to get them to reveal their secrets using optical microscopy, researchers currently need to either mark them with a fluorescent label or attach them to a surface.</span></div> <div><span style="background-color:initial"><br /><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Christoph%20Langhammer_320.jpg" alt="Christoph Langhammer" class="chalmersPosition-FloatRight" style="margin:5px;width:200px;height:195px" />“With current methods you can never quite be sure that the labelling or the surface to which the molecule is attached does not affect the molecule’s properties. With the aid of our technology, which does not require anything like that, it shows its completely natural silhouette, or optical signature, which means that we can analyse the molecule just as it is,” says research leader <strong>Christoph Langhammer</strong>, professor at the Department of Physics at Chalmers. He has developed the new method together with researchers in both physics and biology at Chalmers and the University of Gothenburg. </span></div> <div><br /></div> <div>The unique microscopy method is based on those molecules or particles that the researchers want to study being flushed through a chip containing tiny nano-sized tubes, known as nanochannels. A test fluid is added to the chip which is then illuminated with visible light. The interaction that then occurs between the light, the molecule and the small fluid-filled channels makes the molecule inside show up as a dark shadow and it can be seen on the screen connected to the microscope. By studying it, researchers can not only see but also determine the mass and size of the biomolecule, and obtain indirect information about its shape – something that was not previously possible with a single technique.</div> <div><span style="background-color:initial"><br /></span></div> <div style="font-size:16px"><span style="background-color:initial"><strong>Acclaimed innovation</strong></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">The new technique, nanofluidic scattering microscopy, was recently presented in the scientific journal Nature Methods.

One challenge is that the medicines are very expensive to produce, something that limits global access. Now researchers from Chalmers have invented a material that uses electrical signals to capture and release biomolecules. The new and efficient method may have a major impact in the development of biomedicines and pave the way for the development of electronic pills and drug implants.</b></p><div>​<span style="background-color:initial">The new material is a polymer surface* which at an electrical pulse changes state from capturing to releasing biomolecules. This has several possible applications, including use as a tool for the efficient separation of a medicine from the other biomolecules that cells create in the production of biological medicines. The results of the study were recently published in the scientific journal “Angewandte Chemie”.</span></div> <div> </div> <div>Biomedicines are very expensive to produce due to the lack of an efficient separation technique, and new techniques with a higher drug yield are required to reduce production costs and ultimately the cost of treating patients. </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/KB/Generell/Nyheter/Gustav%20FD%20elektrokemi%20biomolekyler/Gustav_Ferrand_Drake_220x230.jpg" class="chalmersPosition-FloatRight" alt="portrait Gustav Frennad Drake del Castillo " style="margin:5px" />“Our polymer surfaces offer a new way of separating proteins by using electrical signals to control how they are bound to and released from a surface, while not affecting the structure of the protein,” says Gustav Ferrand-Drake del Castillo, who publicly defended his doctoral thesis in chemistry at Chalmers and is the lead author of the study.</div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div>The conventional separation technique – chromatography – binds biomolecules tightly to the surface and strong chemicals are required to make them release, which leads to losses and a poor yield. Many new medicines have proved to be highly sensitive to strong chemicals, which creates a major production problem for the next generation of biomedicines. The lower consumption of chemicals results in a benefit to the environment, while the fact that the surfaces of the new material can also be reused through several cycles is a key property. The process can be repeated hundreds of times without affecting the surface.</div> <div> </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2">Functions in biological fluids</h2> <div> </div> <div> </div> <div> </div> <div>The material also functions in biological fluids with a buffering capacity, in other words fluids with the ability to counteract changes in the pH value. This property is remarkable since it paves the way for the creation of a new technique for implants and electronic “pills” that release the medicine into the body via electronic activation. </div> <div> </div> <div> </div> <div> </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div>“You can imagine a doctor, or a computer program, measuring the need for a new dose of medicine in a patient, and a remote-controlled signal activating the release of the drug from the implant located in the very tissue or organ where it’s needed,” says Gustav Ferrand-Drake del Castillo.</div> <div> </div> <div> </div> <div> </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div>Local, activated drug release is available today in the form of materials that change their state in the event of a change in the surrounding chemical environment. For example, tablets of pH-sensitive material are produced where you want to control the release of a drug in the gastrointestinal tract, which is an environment with natural variations in pH value. But in most of the body’s tissues there are no changes in pH value or other chemical parameters. </div> <div> </div> <div> </div> <div> </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div>“Being able to control the release and uptake of proteins in the body with minimal surgical interventions and without needle injections is, we believe, a unique and useful property. The development of electronic implants is only one of several conceivable applications that are many years into the future. Research that helps us to link electronics with biology at a molecular level is an important piece of the puzzle in such a direction,” says Gustav Ferrand-Drake del Castillo.</div> <div> </div> <div> </div> <div> </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div>Another advantage of the new method is that it does not require large amounts of energy. The low power consumption is due to the fact that the depth of the polymer on the surface of the electrode is very thin, on the nanometre scale, which means that the surface reacts immediately to small electrochemical signals. </div> <div> </div> <div> </div> <div> </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div>“Electronics in biological environments is often limited by the size of the battery and the moving mechanical parts. Activation at a molecular level reduces both the energy requirement and the need for moving parts,” says Gustav Ferrand-Drake del Castillo.</div> <div> </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2">The breakthrough began as a doctoral thesis</h2> <div> </div> <div> </div> <div> </div> <div>The research behind the technique was conducted during the period when Ferrand-Drake del Castillo was a doctoral student in Chalmers professor Andreas Dahlin’s research team in the Division of Applied Surface Chemistry. The project involved polymer surfaces that change state between being neutral and charged depending on the pH value of the surrounding solution. The researchers then succeeded in creating a material that was strong enough to stay on the surface when subject to repeated electrical signals, while also being thin enough to actually change pH value as a result of the electrochemistry on the surface. </div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/KB/Generell/Nyheter/elektroniska%20papper%20Anderas%20Dahlin/Andreas_Dahlin%20220x230.jpg" class="chalmersPosition-FloatRight" alt="portrait Andreas Dahlin " style="margin:5px" />“Shortly afterwards we discovered that we could use the electrical signals to control the binding and release of proteins and biomolecules, and that the electrode material works in biological solutions such as serum and centrifuged blood.

During the manufacturing of these devices, 30 - 70% of the material becomes production waste. Almost 75% of indium is used for ITO manufacturing and it is accepted as a critical raw material due to its importance in the electronic industry. It is a minor element of the earth’s crust and is unevenly distributed. It's recycling from industrial waste is challenging and requires several stages.

The isomer can then be stored in liquid form for later use when needed, such as at night or in winter. The researchers have refined the system to the point that it is now possible to store the energy for up to 18 years. A specially designed catalyst releases the saved energy as heat while returning the molecule to its original shape, so it can then be reused in the heating system.

Graphene is a two-dimensional sheet of carbon atoms arranged into a honeycomb lattice, which provides a large and very sensitive surface area.</p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P">&quot;The carbon atoms have a sphere of electrons above and below the ultra-thin carbon layer. By attaching electrodes at opposite ends, we can measure electrical resistance, making the surface sensitive to anything in the vicinity. In our new study, we show – to our own great surprise – that graphene is so sensitive that we can not only detect whether bacteria are present through small shifts in the electrical charge but also differentiate between different types of bacteria to some extent,&quot; says Ivan Mijakovic.</p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P">Bacteria typically range in size from 0.5 to 5 µm, and have distinct shapes – spherical, rod-shaped and spiral. In addition, most bacteria are encapsulated by a cell wall comprising a peptidoglycan made of negatively charged N-acetylglucosamine and N-acetylmuramic acid. This layer is thicker in gram-positive bacteria and thinner in gram-negative bacteria.</p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P">&quot;This is mainly a prototype to demonstrate the potential of this type of sensor. Without altering anything at the graphene surface, we can therefore detect whether bacteria are present and distinguish their small differences in surface. Naturally, this type of sensor may be useful on surfaces that must be kept completely bacteria-free, such as implants, but our prototype is more a proof of concept that the technology is possible. Now we can take the concept a step further,&quot; explains Santosh Pandit, researcher at Chalmers and the lead author of the study.</p> <div> </div> <h2 class="chalmersElement-H2">The study is p​art of a major European project</h2> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P">The prototype study is therefore only the first step in a major European project aiming to develop sensors that can quickly and accurately identify the pathogenic bacteria that currently pose the greatest problem in healthcare.</p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P">&quot;The human body has thousands of species of bacteria, most of which are actually harmless or often beneficial. We therefore must be able to differentiate between them and thus we need to determine how to functionalise the graphene surface with antibodies or other receptors that are selective to specific bacteria,&quot; says Santosh Pandit.</p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P">The researchers in this international project are therefore collaborating with hospitals to collect the most relevant and problematic pathogens.</p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P">&quot;We then 'shave' the surface of these bacteria to reveal which proteins and biomarkers characterise the pathogens. We can then either create antibodies against the peptides or build small, organic chemical receptors for these surface molecules, as we are doing in collaboration with Nina Kann, Professor in Organic Chemistry at Chalmers,&quot; explains Santosh Pandit.</p> <div> </div> <h2 class="chalmersElement-H2">Hospitals need specific and rapid devices</h2> <h2 class="chalmersElement-H2"> </h2> <h2 class="chalmersElement-H2"> </h2> <h2 class="chalmersElement-H2"> </h2> <p class="chalmersElement-P">The researchers hope that they can use these diverse types of strategies to further develop the prototype version of the graphene sensor into far more advanced chips.</p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P">&quot;Hospitals are looking for a device that is both very specific and very rapid. If this technology succeeds, we would be able to reduce the response time from hours to perhaps minutes so that doctors can respond faster and thus save more lives. The initial target is therefore the bacteria that cause sepsis in hospitals and thus threaten the lives of the most compromised people, but once we have the technology fully developed, we also aim to use it for less urgent applications such as chronic infections or in implants,&quot; concludes Ivan Mijakovic.</p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P"><strong>Text:</strong> Morten Busch, <a href="https://sciencenews.dk/en">Sciencenews </a></p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P"><span style="background-color:initial"><strong>R</strong></span><span style="background-color:initial"><strong>ead the scientific article </strong><a href="https://doi.org/10.3390/s21238085">Graphene-Based Sensor for Detection of Bacterial Pathogens</a></span><br /></p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P"><span style="background-color:initial">by the a</span><span style="background-color:initial">uthors Santosh Pandit, Yanyan Chen, Shadi Rahimi, Vrss Mokkapati, Alessandra Merlo and Prof. Ivan Mijakovic at the Department of Biology and Biological Engineering, Chalmers, and Mengyue Li and Prof. August Yurgens at the Department of Microtechnology and Nanoscience (MC2), Chalmers.</span><br /></p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P"> </p>Thu, 03 Feb 2022 09:00:00 +0100https://www.chalmers.se/en/areas-of-advance/materials/news/Pages/Materials-for-Tomorrow-2021.aspxhttps://www.chalmers.se/en/areas-of-advance/materials/news/Pages/Materials-for-Tomorrow-2021.aspxWatch the seminar – Materials for Tomorrow 2021<p><b>The topic of 2021 Materials for Tomorrow was &quot;Additive Manufacturing – From academic challenges to industrial practice&quot;.

The monomeric ink is extruded from a print head onto a heated bed triggering the frontal polymerization (FP) reaction. Heat released from the polymerization activates adjacent monomer to further the curing process, thereby forming a self-sustaining propagating reaction wave that polymerizes the printed filament. The stiff polymerized segment of the filament can structurally support the printed part during its fabrication to produce three-dimensional (3D) free form printed structures with excellent fidelity. Fabricated parts exhibit a degree of cure of 99.2% and do not require further post-processing.  The addition of nanoparticles and other reinforcement phases allows access to a range of rheological profiles between low-viscosity liquid and free-standing elastomeric gel – all of which frontally polymerize upon thermal activation. This presentation will summarize the characterization of ink rheology for printing, influence of printing parameters, addition of reinforcing fillers, and the resulting mechanical properties of the printed structures.</span></li></ul></div>Wed, 22 Dec 2021 00:00:00 +0100https://www.chalmers.se/en/departments/physics/news/Pages/Material-that-can-both-move-and-block-heat-opens-new-doors.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/Material-that-can-both-move-and-block-heat-opens-new-doors.aspxMaterial that can both move and block heat opens new doors<p><b>​Researchers at Chalmers have participated in a study of a new super-thin material which combines excellent heat conductivity and excellent insulation.

New magnetic and electronic materials are needed for it to regain momentum. As a Wallenberg Academy Fellow Chalmers researcher Yasmine Sassa is developing new combinations of materials that display exotic magnetic states, skyrmions, which could play an important role in future technologies for data storage.</b></p>​<span style="background-color:initial">Our electronic revolution is built upon semiconducting silicon.

These materials have many promising properties for future electronics; when they are combined in a particular manner, they can function as superconductors, or create the right conditions for exotic magnetic states, skyrmions or other topological magnetic states, that could be used for new ways of storing data. If the material is produced as extremely thin films, just a few atoms thick, quantum effects occur that can be used to build quantum computers. </div> <div><br /></div> <div style="font-size:20px">Unexpected magnetic and electronic materials properties<br /></div> <div><br /></div> <div>“My interest in strongly correlated physics started as a Master's student when I took a course about peculiar phenomena in solid-state physics,” says Yasmine Sassa. </div> <div><br /></div> <div>“In this course, we talked about frustrated magnetism and unconventional superconductivity, to name two examples out of many. After that, I had the privilege of extending my knowledge during my Ph.D. and Postdocs. I discovered a fascinating world of new physical properties that cannot be simply explained within classical models. The various correlations give rise to unexpected magnetic and electronic materials properties. If we understand how to control and tune them, we can develop and tailor materials for sustainable technological applications.

But imagine if there was a way the structure could simply build itself? That is exactly what researchers from Chalmers University of Technology, Sweden, now present in an article in the journal Nature. Their work opens up new research opportunities.</b></p>​<span style="background-color:initial">Investigating nano materials can make it possible to study completely new properties and interactions. To be able to do this, different types of ‘resonators’ are often needed – meaning, in this context, an object inside which light bounces around, much like the way sound bounces inside the body of a guitar. Now, researchers working at the Department of Physics at Chalmers University of Technology, have discovered how a previously known form of resonator, made of two parallel mirrors, can be created and controlled in a much simpler way than previously realised.</span><div><br /></div> <div><a href="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Timur%20Shegai-webb_NY.jpg"></a><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Timur%20Shegai-webb_NY.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:135px;height:174px" /><span style="background-color:initial">“</span><span style="background-color:initial">Creating a high quality, stable resonator, such as we have done, is usually complicated and requires many </span><span style="background-color:initial">hours in the laboratory.

The two gold flakes are both positively charged as the aqueous solution covers them with double layers of ions. This causes a repelling electrostatic force, but, due to the simultaneous influence of something called the ‘Casimir effect’, an attracting force is also created, and a stable balance arises, leaving a distance between the flakes of around 150 nanometres. The two nanoflakes orient themsel</span><span style="background-color:initial">ves facing each other, with a cavity formed between them, and they remain stably in this arrangement, for weeks of observations. The cavity then functions as an optical resonator, a device which provides many opportunities to explore various physical phenomena.</span></div> <div><br /></div> <div>Once the gold flakes have formed a pair, they stay in place, and the researchers also observed that, if not actively separated, more and more pieces of gold seek out each other and form a larger grouping. This means that the structure, purely through naturally occurring forces, can grow and create more interesting opportunities for researchers.</div> <div>The structure can be further manipulated by adding more salt to the aqueous solution, changing the temperature, or by illuminating it with lasers, which can lead to some fascinating observations.</div> <div><br /></div> <div>“What is so interesting in this case is that there are colours which appear inside the resonator.
