In vivo approaches to assessing the toxicity of quantum dots

The small size and heavy metal composition of quantum dots (QDs) combined with their growing consumer product and biomedical research applications have generated concern over their safety. In an occupational setting where QD-enabled products are being manufactured, inhalation is a likely route of exposure. Since current research indicates that QDs could cause inflammation and toxicity in the respiratory tract, it is important that a variety of methods be available to further characterize this potential respiratory hazard. This chapter focuses primarily on in vivo methods for modeling the inhalation and assessing the pulmonary toxicity of QDs.
