SmallTalks "Engineering Smart Micro/Nanorobots"

Abstract 

Micro/nanorobots represent cutting-edge tools at the interface of nanotechnology, engineering, and biomedical science. These tiny machines hold significant potential for diverse applications, including advanced drug delivery, environmental remediation, and precision manufacturing. Their ability to navigate and interact with their surroundings at microscopic scales positions them as transformative solutions to complex challenges. However, unlocking the full potential of these robots requires addressing key challenges. Developing smarter micro/nanorobots necessitates advancements in precise motion control, multifunctionality, and adaptability to the surrounding environments. Critical hurdles include the activation of bots under different conditions, facile manipulation and tracking, as well as the controlled pickup and release of cargoes. In this talk, we will present our latest findings on multifunctional micro/nanorobots featuring advanced attributes such as multi-color emission, reversible propulsion, magnetic control, and directional cargo transportation. Future efforts will focus on adapting these machines for biomedical applications, including multimodal imaging, thermotherapy, and targeted drug delivery. These developments represent a significant step toward creating versatile and efficient robotic systems capable of addressing real-world challenges at the nano- and microscale.
