Plasmon coupling measures up

Article Abstract:

The coupling of localized surface plasmon resonances offers a potential alternative to Forster resonance energy transfer (FRET) for measuring nanometer scale distances. Taking advantage of incident light to excite electron-density waves localized along the surface plasmon resonance LSPR (localized surface plasmon resonance) as an alternative to FRET for monitoring nanometer-scale distances.

Finding enzymatic gold on silver surfaces

Article Abstract:

The surface enhanced resonance Raman scattering enables rapid and sensitive identification of lipase activity and enantioselectivity on dispersed silver nanoparticles. This concept of surface enhancement resonance Raman scattering to measure lipase activity on silver nanoparticles at ultra-low levels facilitates enzyme characterization and optimization.

A molecular ruler based on plasmon coupling of single gold and silver nanoparticles

Article Abstract:

The plasmon coupling is used to monitor distances between single pairs of gold, silver nanoparticles. The directed assembly of gold and silver nanoparticle dimers in real time is followed, and the kinetics of single DNA hybridization events is studied.
