Do quantum dots penetrate damaged skin?
The August issue of the journal Nano Letter (ASAP Article, 10.1021/nl801323y) features a paper entitled ‘In Vivo Skin Penetration of Quantum Dot Nanoparticles in the Murine Model: The Effect of UVR’, which the researchers present the results of a study that aimed to examine the impact of UV-radiation (UVR) on nanoparticle skin penetration by employing an in vivo semiconductor quantum dot nanoparticle (QD) model system (i.e. a system used to provides enhanced NP imaging capabilities). The researchers report that ‘low levels of penetration were seen in both the non-UVR exposed mice and the UVR exposed mice.
