Abstract

In the poster a novel approach of a single nanoparticle binding event detection is presented, allowing detection of gold nanoparticles down to 40 nm diameter. The system is based on a surface plasmon resonance excited on an optical grating combined with a supercontinuum laser and a tuneable filter allowing a use of an optimal spectral region. A large visual field enables a detection of binding events at low concentrations, with a possible application in the field of biochemical analysis.
