Toxicological considerations when creating nanoparticle-based drugs and drug delivery systems

Nanotechnology has significant potential for advancing therapeutic efficacy and imaging in cancer; however, these agents can be toxic. Therefore, toxicity needs to be considered when selecting nanoparticles for a particular application. Methods for assessing nanoparticle toxicity need to be improved and standardized across all nanotechnology platforms in order to speed up the application of nanoparticle use in humans.
