Distance and orientation dependence of heterogeneous electron transfer: a surface-enhanced resonance Raman scattering study of cytochrome c bound to carboxylic acid terminated alkanethiols adsorbed on silver electrodes
Article Abstract:
Functionalized self-assembled monolayer (SAMs) in combination with silver film over nanosphere (AgFON) electrodes affect a general solution to the problem of fabricating stable, biocompatible SERS-active surfaces for use in structural studies of surface-confined biomolecules. The biomimetic/biocompatible character of these AgFON/S(CH2)xCOOH surfaces coupled with their unusual stability and large surface enhancement factors greatly extends the usefulness of SERRS in the study of surface-confined biomolecules.

A nanoscale optical biosensor: Real-time immunoassay in physiological buffer enabled by improved nanoparticles adhesion
Article Abstract:
Evidence is provided that triangular Ag nanoparticles LSPR biosensors are applicable to real world conditions, and these LSPR biosensors were optimized for strength, reusability, and in vivo applicability. It was demonstrated that Ag nanoparticle biosensors retain most of the qualities of conventional SPR, by providing sensitive and selective monitoring of binding of an analysis of an analyte to a nonoparticle surface.

A nanoscale optical biosensor: The long range distance dependence of the localized surface plasmon resonance of noble metal nanoparticles
Article Abstract:
The long range LSP R distance dependence of nobel metal nanoparticles will be probed using multilayer formation of 11-mercaptoundecanoic acid and Cu(super 2+) ions. It was shown that using nanotriangles instead of nanohemispheres, Ag instead of Au, or larger aspect ratio nanoparticles, can increase the sensing volume of the nanoparticles.
