Screening and evaluation of conditions for separating the skin into epidermis and dermis by microwave irradiation. a Skin tissue was irradiated with microwaves under nine conditions and separated into epidermal and dermal tissues. Left and right panels show skin samples before and after irradiation, respectively. In the right panel, single, double, and triple white circles show non-separable, partially separable, and completely separable conditions, respectively. Scale bars: 1 cm. Skin homogenates were mixed with nAg100 to obtain a final Ag concentration of 100 ng/mL, and irradiated at 200 W for 30 s, and analyzed via sp-ICP-MS. b The nAg (black bars) and Ag+ (shaded bars) recovery rates and c average particle diameters are presented. The dashed line represents the initial particle size. The data have been expressed as mean ± S.D. (n = 3)
