Using coatings developed by Quantum Dot, Carnegie Mellon University scientists have been able to use nanoparticles for the long-term imaging of living mice. The nanoparticles, which are fluorescent crystals named quantum dots, can circulate inside the mice for many hours, which allows scientists to determine where these fluorescent signals are located for at least four months. These signals will help scientists locate targets at the molecular level. Electron microscopy allowed the scientists to verify the quantum dots' locations inside the mice. Scientists coated the quantum dots with a polyethylene glycol amine molecule and an amphophilic-polyacrylic acid polymer, which accounts for the dots' increased longevity, especially for in vivio biological studies. The coatings allow the quantum dots to be chemically stable and to attach easily to biological molecules. Other molecules can be developed using this chemical process. The Qdots, which Quantum Dot has named, can be used for several drug-discovery applications.
