Abstract

This paper discusses the efficiency of the attenuation of UV radiation by nanoparticles of titanium oxide (TiO₂) incorporated into the horny layer of the skin. The distribution of TiO₂ particles was determined experimentally. A program implementing the Monte Carlo method was used to model photon propagation in a 20-μm thick horny layer of the skin, partially filled with TiO₂ particles. The dependences are obtained for the transmitted, reflected, and absorbed components of UV radiation with a wavelength of 310 nm as a function of the concentration of TiO₂ particles of various sizes (40-175 nm). It is established that the most efficient particles for protecting the deep layers of skin containing living and, in particular, immune-competent cells from UV radiation are particles 62 nm across.
