ABSTRACT
Nanomaterials have been proposed for use in many biological applications, although little is known of their toxicity, potential mutagenic, carcinogenic or teratogenic effects, or overall risk to human health. To avoid past-mistakes made with new technological innovations when chemicals or drugs were released prior to a broad-based risk assessment, information is needed regarding the potential toxicological impact and biological effects of exposure for their medical, occupational health and environmental effects (1).
