Microscale Microrobots for Cellular Manipulation
Inspired by the biological motors at the micron and nanoscale, various microscale robots have been developed that can be actuated in cellular environments and are on the same length scale as biological motors. However, motion at such low length scales is hard to control due to thermal fluctuations. In our group we have developed microscale robots that can be actuated using magnetic fields in dense cellular environments. In this talk I will present the fabrication and manipulation of magnetic Janus microrobots which can be navigated in tight channels mimicking blood vessels. I will also demonstrate automated control of microrobot motion and its application for cellular manipulation. This precise wireless control of Janus microrobots is also able to transfer cells against fluid flows.
