Multi-functional compound micromachines for targeted therapy

We have fabricated multi-functional compound micromachines in our lab using 3D direct laser writing and selective physical vapour deposition of magnetic materials. Microtransporters with a wirelessly controlled Archimedes screw pumping mechanism were engineered for spatiotemporally controlled collection, transport, and delivery of micro particles, as well as magnetic nanohelices inside microfluidic channels. In this project, these mciromachines were engineered to noninvasively collect biological samples from remote pathological sites for diagnostic purposes using magnetic and acoustic actuation.
