Semi-quantitative physical property analysis of nAg100 and Ag+ applied to mouse skin in vivo. Firstly, mouse skin was exposed to nAg100 and Ag+ (20 μg Ag/cm2). Five days after exposure, quantification, and evaluation of physical properties of Ag in epidermis, dermis, and blood were conducted via ICP-MS and sp-ICP-MS, respectively. a Ag concentrations and b particle rates detected in the epidermis, dermis, and blood. c The average diameter of particles detected in the epidermis and dermis. The dashed line represents the initial particle size. All data have been expressed as mean ± S.E. (n = 3). *p < 0.05 (Student’s t test)
