Silicon nanocrystals map location of spreading tumors

Nano-sized fluorescent particles known as quantum dots have shown promise as powerful imaging agents capable of detecting a wide range of diseases, but these nanoparticles are usually made with toxic metals such as cadmium. Now, researchers at the University of Buffalo have developed a novel synthetic method that enables them to design and create biocompatible fluorescent nanocrystals made of non-toxic silicon.
