Quantized plasmon quenching dips nanospectroscopy via plasmon resonance energy transfer

Nat Methods. 2007 Dec;4(12):1015-7. doi: 10.1038/nmeth1133. Epub 2007 Nov 18.

Abstract

We observed quantized plasmon quenching dips in resonant Rayleigh scattering spectra by plasmon resonance energy transfer (PRET) from a single nanoplasmonic particle to adsorbed biomolecules. This label-free biomolecular absorption nanospectroscopic method has ultrahigh molecular sensitivity.
