Abstract

The potential ability of SiO2(Ag)–Si nanosystem to induce oxidative stress and death of human peripheral blood cells involving reactive oxygen species was studied using a double-color cytoflourometry method. This SiO2(Ag)–Si system with silver dendrites obtained via the metal deposition into the pores of SiO2 template on a silicon substrate was shown to increase the concentration of ROS but not cause the cell death associated with oxidative stress. Such systems are prospective for the analysis of biological substances with Raman scattering.
