Modulation of a photoswitchable dual-color quantum dot containing a photochromic FRET acceptor and an internal standard
Photoswitchable semiconductor nanoparticles, quantum dots (QDs), couple the advantages of conventional QDs with the ability to reversibly modulate the QD emission, thereby improving signal detection by rejection of background signals. Using a simple coating methodology with polymers incorporating a...
