บทคัดย่อ/คำอธิบาย :

Quantum dots have been used in biomedical research for imaging1, 2, diagnostics3, 4 and sensing purposes5, 6. However, concerns over the cytotoxicity of their heavy metal constituents7, 8 and conflicting results from in vitro7, 9 and small animal10, 11, 12, 13, 14 toxicity studies have limited their translation towards clinical applications. Here, we show in a pilot study that rhesus macaques injected with phospholipid micelle-encapsulated CdSe/CdS/ZnS quantum dots do not exhibit evidence of toxicity. Blood and biochemical markers remained within normal ranges following treatment, and histology of major organs after 90 days showed no abnormalities. Our results show that acute toxicity of these quantum dots in vivo can be minimal. However, chemical analysis revealed that most of the initial dose of cadmium remained in the liver, spleen and kidneys after 90 days. This means that the breakdown and clearance of quantum dots is quite slow, suggesting that longer-term studies will be required to determine the ultimate fate of these heavy metals and the impact of their persistence in primates.
