Luminescent nanoparticles as labels for bioassay

Luminescent nanoparticles of different nature present a perspective tool for research and analysis. Application in assay allows to increasing of assay sensitivity, comparing to coloured nanoiparticles without the assay procedure complication. Additional perspectives are related with the sensitivity of luminescence nanoparticles to the environment properties, including presence of quenchers. FRET application discussed in details.
