[Estimation of ROS in the Presence of Biologically Active Substances by Porous Silicon Fluorescence].

The fluorescence spectra of the porous silicon modified by water solutions of biologically active materials and materials of biological origin are recorded as well as the fluorescence spectra of the porous silicon modified by lecithin monolayers grown on the surface of water solutions of the biologically active materials. The analysis of the obtained spectra made it possible to conclude on the effect of the studied materials on the content of ROS.
