Abstract:
Nano and micromotors can be defined as tools, with a size ranging from few nanometers to micrometers, that can convert a chemical fuel, light, magnetic, or acoustic energy input into autonomous motion to perform several tasks.1 Many researchers have selected magnetic fields as the active external actuation source based on the advantageous features of this actuation strategy such as remote and spatiotemporal control, fuel-free, high degree of reconfigurability, programmability, recyclability, and versatility. In this talk, I will discuss about the various actuation mechanisms of the “Magrobots” (abbreviated for magnetic micro/nano robots) which are inspired from the bacterial motion of cilia and flagella.2 The shape of the Magrobots also plays an important role in the fabrication techniques.3 The beauty of these Magrobots lies in the fact that their biomimicking property have widespread applications in the field of water remediation (pollution removal)4, cell manipulation, targeted drug delivery, biopsy5, assisted fertilization, magnetic image guided tracking and so on, making them promising candidates for the new generation biomedical robots.
