A review of published toxicology studies argues that there are as yet no ways to predict which quantum dots will be toxic and which will be safe, making it necessary to test each type of quantum dot for toxicity before reaching any conclusions about their clinical utility.

Carbon nanotubes have already found many valuable applications in nanotechnology. Now researchers are adding yet another potential use for these unique nanomaterials: as a detector for specific sequences of DNA. The work suggests that carbon nanotubes could be the basis for ultrasensitive devices for detecting pathogens such as anthrax and DNA mutations that cause genetic diseases, as well as leading to a more precise tool for understanding genetic mechanisms inside cells.
