The cover picture shows a pathology image of a tissue from Sprague–Dawley rats exposed to quantum dots (shown as green and red glowing spheres) after intravenous injection for toxicity analysis. The results show that ZnS-capped CdSe quantum-dot formulation does not induce a toxic response to the animal, despite the slow degradation of quantum dots in vivo. Previous studies show that metabolized quantum dots are toxic to cell cultures; in contrast, these results show that the toxicity of nanoparticles in vivo may differ in vitro. By surveying different quantum-dot compositions, sizes, and surface chemistry in animal models, the toxicity of quantum dots can be determined.
