We report the first observation of quantized plasmon quenching dips in the resonant Rayleigh scattering spectrum by plasmon resonance energy transfer (PRET) from a single nanoplasmonic particle to adsorbed metalloproteins cytochome c. PRET permits to develop an innovative label-free biomolecular absorption nanospectroscopy with sub-100 nm spatial resolution and ultrahigh molecular sensitivity. The multiplexed nanoplasmonic PRET probes may also allow in-vivo nanospectroscopic molecular imaging of metalloproteins in living cells
