Magnetic Nano-Swimmers for Biological Applications

The idea of tiny vessels roaming around in human blood vessels working as surgical nano-robots was first proposed by Richard Feynman, a vision that has triggered imagination in scientists and non-scientists alike.  With current advances in nanotechnology, there have been several strategies to realize this dream of a "nano-voyager", which is of both fundamental and technological interest. My talk will focus on a system of artificial helical nano-structures that can be actuated with small magnetic fields to move through fluidic media in a highly controllable fashion, share the recent promising results pertaining to biotechnology and describe the many challenges that lie ahead.
