360-390 / 1000+ results research Determination of the cuticula thickness of human and porcine hairs and their potential influence on the penetration of nanoparticles into the hair follicles
Nanoparticles penetrate hair follicles better when their size matches the cuticula thickness.
research Penetration of silver nanoparticles into porcine skinex vivousing fluorescence lifetime imaging microscopy, Raman microscopy, and surface-enhanced Raman scattering microscopy
Silver nanoparticles can penetrate porcine skin up to about 15.6 μm, possibly through hair follicles.
research In vitro and in vivo study of dye diffusion into the human skin and hair follicles
Dyes can penetrate human skin and hair follicles up to 1.2 mm deep and the sebaceous gland can store dye; Indocyanine Green lotion was made for safe dyeing and monitoring.
research Use of confocal microscopy for nanoparticle drug delivery through skin
Confocal microscopy is useful for studying how nanoparticles interact with skin.
