Chiroptical effects in inorganic nanostructures
I will describe several systems where plasmonic or excitonic nanostructures interact with chiral molecules and circular dichroism (CD) appears in the plasmonic or excitonic resonances.
In particular: the enhancement of CD using plasmonic nanostructures interacting with small quantities of chiral molecules will be described. Size and material dependent study of induction of CD in exciton transitions in colloidal semiconductor quantum dots as a tool to learn on the mechanism of the interaction of the molecules with the dots and about the exciton states. Finally, I will discuss the synthesis and chiroptical properties of nanostructures made of intrinsically chiral materials.
