• [Display omitted] •Green synthesis of ZnO nanoparticles using A. indica leaf by different calcination.•Prepared ZnONps characterised and compared to the lower calcination.•The structural morphology and antimicrobial activity of ZnONps were investigated.•To enhanced the Hydrophobicity and UV-protection for biomedical applications. In this study, ZnO nanoparticles were green-synthesized from Acalypha indica leaf extract using zinc acetate as a precursor. The prepared ZnO nanoparticles were calcined at three different temperatures, namely 100, 300, and 600 °C. The structure/morphology of the green-synthesized ZnO nanoparticles was ascertained through X-ray diffraction, particle size analysis, scanning electron microscopy, transmission electron microscopy, and surface area analysis techniques. It was observed from the physico-chemical and biological characterization studies that ZnO nanoparticles calcined at high temperature (600 °C) exhibit high surface area (230 m2 g−1) and small particle size (20 nm) with good antibacterial activity against Escherichia coli (22.89 ± 0.06 mm) and Staphylococcus aureus (24.62 ± 0.08 mm). In addition, cotton fabrics coated with these nanoparticles showed higher UV-protection (87.8 UPF), hydrophobicity (155°), and maximum zone of bacterial inhibition against E. coli and S. aureus (25.13 ± 0.05 mm and 30.17 ± 0.03 mm) than those coated with particles calcined at 100 °C and 300 °C. High temperature calcination has a vital role in the crystallization of the particles towards nanoscale with increased resistivity to UV exposure, washing treatments, and microbial infection in fabrics. Thus, the cost-effective ZnO nanoparticles obtained through green synthesis method proves their potential applications in the field of biomedical, textile, and cosmetic applications.
