Microrobots for Medical Procedures
September 20, 2016 | Terry Sharrer
Novel methods of drug delivery inside the body is a promising area for research as it may make precise placement of medications possible without posing problems of systemic adverse effects. Swiss scientists are working on microrobots made of hydrogel and magnetic nanoparticles. Heat causes the structures to unfold (thereby grasping drugs) and electromagnetic fields allow them to “swim” to different locations. The design model for this is Trypanosoma brucei. the protozoa responsible for African sleeping sickness. MORE
