- Materials preventing biomaterial associated infection. Martin Andersson, Professor of Chemistry and Chemical Engineering, Applied Surface Chemistry.Chalmers University of Technology.
Bioink Design for Printing of Unified, Multi-material Constructs
While 3D printing has enormous potential to fabricate living materials, a current lack of diversity in bioink materials is a major limitation. A cell’s behavior is directly influenced by its surrounding microenvironment; thus, ideally each cell type would be printed in its own customizable bioink. To fulfill this need for a universally applicable bioink strategy, we developed a versatile mechanism that is completely cell compatible and works with any type of biopolymer. We term this family of materials UNIversal, Orthogonal Network (UNION) bioinks, and we envision that these materials will assist in the future fabrication of complex, cell-laden constructs.
Sarah Heilshorn is Professor and Associate Chair in the Department of Materials Science & Engineering at Stanford University. She holds courtesy faculty appointments in the Departments of Chemical Engineering and Bioengineering and is a Bass University Fellow in Undergraduate Education. Her laboratory integrates concepts from materials science and protein engineering to design new, bioinspired materials.
Development of Antibacterial Surfaces for Medical Devices
The surface of medical devices such as implants play a major role in the integration process and several surface modifications have been clinically introduced. However, novel surfaces designed for improved integration may also be prone to bacterial colonization, resulting in that highly integrating materials could possess higher risks for biomaterial associated infection (BAI), leading to a status que or even poorer outcome over the life span of the implant. As a consequence, it is important that also bacterial interactions are taken into account when new implant surface modifications are translated into the clinic. An aim would be to develop implant surfaces that selectively promote desired tissue formation and at the same time avoid bacterial attachment and biofilm formation.
Martin Andersson is Professor and Deputy Head of Department of Chemistry and Chemical Engineering at Chalmers University of Technology.
