Генерация активных форм кислорода нанокомпозитами AgInS-=SUB=-2-=/SUB=-/TiO-=SUB=-2-=/SUB=- под действием излучения УФ и видимого диапазонов

In this work, we synthesized nanocomposites consisting of an AgInS2 core and a nanostructured TiO2 shell. Primary characterization showed that, as a result of synthesis, particles with an average diameter of 12 nm and a TiO2 shell thickness of 4 nm were formed. It demonstrated that the synthesized nanocomposites can efficiently generate superoxide anion and hydroxyl radical under the influence of UV radiation and superoxide anion under the influence of visible radiation. Efficient generation of superoxide anion under the action of visible radiation lying in the TiO2 transparency range indicates efficient photoinduced electron transfer from the core to the shell of nanocomposites, and it makes such systems promising for the treatment of bacterial infections.
