New study of nanoparticle skin penetration

As engineered nanoparticles (ENPs) become increasingly common in consumer products and the environment, concern over their possible effects on human health also rises. There is concern over the possible penetration of human skin by ENPs. "However, the evidence whether nanoparticles can infiltrate into underlying tissues is conflicting . . .  clarification of the issue is essential. . .."
With this in mind, Christopher. S.J. Campbell of Mango Business Solutions, L. Roderigo Contreras-Rojas, M. Begona Delgado-Charro, and Richard H. Guy, of the University of Bath Department of Pharmacy & Pharmacology have recently published a study "Objective assessment of nanoparticle disposition in mammalian skin after topical exposure" in the Journal of Controlled Release discussing the results of their attempts to measure the extent and depth that ENPs are able to penetrate the skin, in the case of this study the specially cleaned and prepared skin of a pig.
