Structural characterization, spectral investigation and antimicrobial studies Of ZnWO4 and Zn0.9Cu0.1WO4 nanoparticles synthesized by microwave and sucrose mediated solgel method

•Antimicrobial potentials of ZW-S, ZCW-S, and ZCW-M NPs. were investigated.•Particle size of NPs through XRD were 20.19, 19.18 and 21.12 nm.•NPs exhibited characteristic band gap of 2.88, 2.53 and 2.59 eV.•ZCW-M NPs adopted “Apoptosis” mechanism for inhibiting fungal cells.•The ZCW-S NPs antibacterial activity is more than the standard azithromycin.
