Some aspects of quantum dot toxicity

Quantum dot toxicity has become a hot topic in recent years due to the emergence of semiconductor nanoparticles as highly efficient biological imaging agents. The use of quantum dots in biology is arguably the most successful application of pure nanotechnology in recent times, although unfortunately, the most useful semiconductor particles contain elements that are often thought to be detrimental to health and the environment. In this article, we explore some key reports on this issue.
