Fluorescent probes group

Molecular fluorescence by itself and enhanced by interaction with metallic nanoparticles is used to characterize environments at the molecular level as well as to monitor their dynamics. For this aim spectral properties, anisotropy, and fluorescence lifetime are studied down to the single molecule level.
