Photocatalytic and antibacterial biomimetic ZnO nanoparticles

Societal impact : For the first time, biomimetic synthesis of crystalline and spherical ZnO nanoparticles from Saccharomyces cerevisiae is reported. Photocatalytic degradation of industrial pollutant 4-nitrophenol (4-NP) via biosynthesized ZnO NPs is shown. The antibacterial activity of biosynthesized ZnO NPs against E. coli 1302 is demonstrated.
