Chirality and Chiroptical Effects in Nanostructures

Optical activity in inorganic nanostructures can be made much more intense than in chiral molecules It may be the result of forming nanostructures with chiral shapes made of metals or semiconductors but also arise from interaction of achiral inorganic nanostructures with chiral molecules In the latter case chiroptical spectroscopy may provide new information on the interaction of the chiral molecules with the inorganic surface Several examples demonstrating the different effects will be described
