Cadmium-based quantum dots (QDs) have shown their values in disease diagnosis, cellular and molecular tracking, small-animal imaging, and therapeutic drug delivery. However, the potential safety problems of QDs, mainly due to their nanotoxicities by unclear mechanisms, have greatly limited its applications. To reverse this situation, we investigated the underlying biological mechanisms of the toxicity...
Poly(amidoamine) (PAMAM) dendrimers, are among the most common classes of dendrimers that are intended for a wide range of biomedical applications and extensively investigated for brain-specific drug delivery, imaging and diagnosis. Unfortunately, neurotoxicity of PAMAM dendrimers, the underlying mechanism of which is poorly-elucidated, poses a far-reaching challenge to their practical applications...
