Upconverting Nanoparticles (UCNPs) are luminescent nanomaterials ranging from 1 to 100 nm in size. UCNPs absorb multiple photons of near-infrared (NIR) light and convert them into higher-energy light regions, ranging between ultraviolet (UV) and visible frequencies of the electromagnetic spectrum. The many unique properties (large anti-Stokes shifts, steady and long-lived luminescence, high resistance to photobleaching and no photoblinking) have attracted interest from the biophotonics field and have already been applied in microscopy, multi-modal imaging, temperature sensing, and highly sensitive bioassays.
ACS Material provides oil dispersible, ligand-free and modified/coated UCNPs. These are available immediately for scientific research in fluorescence imaging, biodetection, photodynamic therapy, fingerprinting, labeling, photoactivation of anti-cancer drugs and biomolecules. Other possible use-cases for UCNPs include biomedical imaging, in vitro and in vivo applications as well providing a novel technique in drug delivery systems. Read More »
