Photocatalytic and antibacterial biomimetic ZnO nanoparticles

Abstract

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