Fluorescent quantum dots are valuable tools used to tag and image biological processes in live animals. However, precise fluorescent imaging at the cellular and molecular levels has not been possible because of non-specific fluorescence and light scattering by surrounding tissues. Now researchers have created short wave infrared (SWIR) quantum dots that resolve many of these problems. The system was used in live mice to image working organs, take metabolic measurements, and track microvascular blood flow in normal brain and brain tumors……..
