Our research activities are broadly focused on single molecule energy and charge transfer studies of nanomaterials with potential in solar energy conversion and biosensing. This includes hybrid organic/inorganic nanomaterials, biological/inorganic nanostructures and photonic (conjugated) polymers. We use self-assembly methods to connect various donor and acceptor components and to obtain nanostructures with controlled optical behavior. We also develop ultrasensitive nanoscale optical imaging and probing methods for charge and energy transfer studies, down to single molecule sensitivity.
