Fluorescence quenching using plasmonic gold nanoparticles

This communication describes the study of fluorescence quenching in a new fluorescent laser dye ADS680HO is attached to gold nanoparticles of size 4–12 nm. Photo physical properties confirms that it is due to size, shape, coupling between nanoparticles with laser dye ADS680HO, and energy transfer between dye and nanoparticles. Fluorescence quenching leads to advancement in biomolecular labeling and fluorescence patterning.
