New genre of sugar-coated 'quantum dots' for drug delivery

(PhysOrg.com) -- Scientists in Switzerland are reporting an advance that could help tap the much-heralded potential of “quantum dots”— nanocrystals that glow when exposed to ultraviolet light — in the treatment of cancer and other diseases. They are publishing the first study showing that giving quantum dots an icing-like cap of certain sugars makes these nanoparticles accumulate in the liver but not other parts of the body.
