Biosensing applications of Plasmon Resonance in gold nanoparticles
Online Presentations | 02 Aug 2007 | Contributor(s):: Karina Moore
Light can be used to excite plasmon resonance in gold nanoparticles. Plasmon resonance occurs on the nanoscale as the particles become excited and plasmon oscillations arise in each particle of a pair of metal nanoparticles. There is plasmon coupling between the neighboring particles as the...

Molecular Interferometry
Online Presentations | 26 Jun 2007 | Contributor(s):: David D. Nolte
While single-molecule detection through fluorescence has now become common-place, there has been no analogous single-molecule capability using direct detection approaches such as interferometry. This limitation is slowly yielding to high-speed interferoemtric detection that is pushing the...
