which can dominate the scattering signal and mask the presence of smaller particles. It assumes spherical particles and may not provide accurate size information for non-spherical or highly ...

Previous work has shown that the effective light scattering by gold nanoparticles can be used to examine single-molecule enzyme activity in vitro. To visualize the scattering signal in the live ...

It is ideal for macro-molecular studies and submicron particle sizing. At the heart of the BI-200SM is the TurboCorr correlator which is an entirely digital, high speed, signal processor which can be ...

SERS combines the specificity of Raman spectroscopy with the signal enhancement provided by the interaction between the molecule and the metal surface, enabling highly sensitive detection and ...
