Quantum dot nanoparticle probes, used to target and image tumors through the incorporation of antibodies that bind to the target cancer cells. In this image, several quantum dots are attaching to a tumor on the wall of a blood vessel. Quantum dots can be tuned to emit a variety of wavelengths, making them useful probes for real-time in vivo imaging.
