a Schematics for exciton transporting mechanism in the genetically engineered M13 phage based light harvesting system. Magnified M13 phage surfaces show the energy-transfer networks between chromophore-binding sites for M13CF (left) and M13SF (right), respectively. Insets show schematic networks of energy transport by exciton hopping in the M13CF and the M13SF, respectively. b Absorption and emission spectra of free donor (DN) and free acceptor (AC). c Fluorescence spectra of donor under 495Â nm. Significant fluorescence quenching is observed in the presence of M13 phage. The upper inset is a fluorescence microscope image of the M13SF-DN. The bottom inset shows the change in emission colour of donor molecule as FRET occurs [109].
