Photothermal effect of laser radiation on the electrical properties of cartilage impregnated with magnetite nanoparticles

A photothermal study of laser effects on the electrical conductivity of an articular cartilage impregnated with magnetite nanoparticles is conducted. The behavior of the electric conductivity of cartilage impregnated with magnetite nanoparticles from solutions of different concentrations (0.4 to 10 mg/mL) and depending on the dynamics of laser heating from 20 to 40°C is studied. The growth kinetics of the electrical conductivity induced by laser heating in samples of intact cartilage tissue of animals and those of the same tissue impregnated with magnetite nanoparticles are compared.
