Abstract          We demonstrate that gold nanoparticles (GNPs) with self-assembled monolayer (SAM)can function as all-optical nanoscale biomolecular detectors that monitor in situ resonantbiomolecules, such as Cytochrome c. By tethering resonant biomolecules to Aunanoprobes, the binding events of Cytochrome c onto 50-nm Au nanoprobes yieldcharacteristic spectral dips in scattering spectra of Au nanoprobes due to plasmonresonance energy transfer (PRET). The quenching dip depth of the single nanoprobespectrum is found to be a function of incubation time (t) and concentration of Cytochromec, which provides a real-time and nanoscale measurement and quantification ofCytochrome c.
