The use of nanosized materials is rapidly increasing, both in technological applications for daily use and in biomedical research. The use of these materials, especially for biomedical purposes is however still limited as the potential toxicity of nanomaterials warrants a lot of caution. The generation of a lot of toxicological data concerning nanomaterials sometimes creates a negative perception...
The interest in the biomedical use of highly fluorescent and photostable nanoparticles such as quantum dots (QDots) is vastly increasing. One major hurdle that impedes QDot use in live cells and animals is their potential toxicity. Here, we employ a recently described multiparametric setup to determine the concentration at which common polymer-coated QDots become non-cytotoxic. We found that toxic...
