| Description |
The ubiquitous influence of chirality in the biological world include the differential pharmaceutical activity of right and left handed drug molecules, locomotion of micro-organisms through the rotation of helical (and therefore chiral) flagella, and many more. My talk will focus on a system of artificial chiral nanostructures that can be actuated with small magnetic fields to move through fluidic media similar to various bacterial species. It has been possible to achieve extremely well controlled motion with these nanostructures, which can be used in various biomedical applications, and can also serve as a model system to understand certain complex biological processes. Interestingly, these structures can be engineered to have strong chiro-optical response, which can give rise to novel collective phenomena.
