abstract = {A large number of inorganic materials form crystals with
chiral symmetry groups. Enantioselectively synthesizing
nanostructures of such materials should lead to interesting
optical activity effects. Here we report the synthesis of
colloidal tellurium and selenium nanostructures using
thiolated chiral biomolecules. The synthesis conditions are
tuned to obtain tellurium nanostructures with chiral shapes
and large optical activity. These nanostructures exhibit
visible optical and chiroptical responses that shift with
size and are successfully simulated by an electromagnetic
model. The model shows that they behave as chiral optical
resonators. The chiral tellurium nanostructures are
transformed into chiral gold and silver telluride
nanostructures with very large chiroptical activity,
demonstrating a simple colloidal chemistry path to chiral
plasmonic and semiconductor metamaterials. These materials
are natural candidates for studies related to interactions
of chiral (bio)molecules with chiral inorganic surfaces,
with relevance to asymmetric catalysis, chiral
crystallization and the evolution of homochirality in
biomolecules.},
