Abstract

We observe that introducing a layer of reduced graphene oxide between electrochemically deposited gold nanoparticles and natural photosynthetic Fenna–Matthews–Olson (FMO) complex from green sulfur bacteria, results in an increase of the fluorescence emission of the FMO. This increase is not accompanied with any substantial change of the fluorescence dynamics. Our findings indicate that incorporating graphene-based materials in hybrid assemblies yields better performance of such structures, thus holds promise for designing biosensing and optoelectronic devices.
