Photoconverters with organic semiconductors and photosynthetic bacteria: Positioning the bacterial Reaction Center in nanostructures

Photosynthetic Reaction Center (RC) is a transmembrane photoenzyme capable of converting absorbed photons into electron-hole pairs with almost unitary efficiency. The unique properties of this natural photoconverter attract considerable interest for its use as functional component in nanomaterials and bioelectronics devices. Implementation of RC into nanostructures or anchoring on devices' electrode surfaces require the development of suitable chemical manipulation. Here we report our methods to embed this protein in soft nanostructures or to covalently attach it on surfaces without denaturating it or altering its chemical properties.
