Objective: To develop a method of simulation of infected area and depth-controlled burn wound through the use of laser radiation. Material and methods: The contact surgical fiber laser at heating mode of 220°C within 2 с has been used in a surgical experiment on 50 white lab rats under the control of a thermal imager, copper laser nozzle on the skin of an animal. Burn wounds have been infected. Results: Controlled single laser effect by the developed method helps speed up the simulation and subsequent infection of burn wounds, all layers of the skin. Conclusion. The infected burn wound model is suitable for the development of effective combined surgical treatment.

Optical properties of the films with high concentration of semiconductor core-shell CdSe/ZnS nanocrystals under action of visible laser radiation in a wide range of power densities have been investigated. It's shown that in the films with ultimate concentration ofthe nanocrystals a quantum-size effect is observed. High concentration of the nanocrystals in the films and the presence of dipoles caused by nanoparticles asymmetry lead to strong shift of quantum-size peaks in absorption and luminescence spectra compared to the solution and the films with low concentration of the nanoparticles. The altitude of the shift depends on the thickness of the films and varies from 35 nm to 50 nm. The luminescence spectra of the films don't change until the power density of exciting laser radiation exceeds 1x106 W/cm2. The regimes of laser action on the films of the nanoparticles with power densities beyond the threshold of films destruction (from 5x10^6 W/cm^2 to 1x10^9 W/cm^2) have been investigated.
