“…We formed our multilayered hybrid structures using the modified Langmuir-Blodgett technique [43]. Briefly, colloidal solutions of titania nanoparticles and CdSe QDs in toluene were dropped onto the water surface, and titania NP or CdSe QD layers were formed on the water-air interface due to toluene evaporation; then, the layers were transferred to the dielectric substrates (See Section S2 and Figure S2 of the Supplementary Materials for details).…”

Titania nanoparticle/CdSe quantum dot hybrid structures are a promising bactericidal coating that exhibits a pronounced effect against light-sensitive bacteria. Here, we report the results of a comprehensive study of the photophysical properties and bactericidal functionality of these hybrid structures on various bacterial strains. We found that our structures provide the efficient generation of superoxide anions under the action of visible light due to electron transfer from QDs to titania nanoparticles with ~60% efficiency. We also tested the antibacterial activity of hybrid structures on five strains of bacteria. The formed structures combined with visible light irradiation effectively inhibit the growth of Escherichia coli, Bacillus subtilis, and Mycobacterium smegmatis bacteria, the last of which is a photosensitive causative agent model of tuberculosis.
