In view of advantages of green synthesis, a novel green route for synthesis and stabilization of zinc oxide nanoparticles (ZnONPs) using aqueous extract of Solanum rantonnetii leaves at room temperature. The formation of ZnONPs is monitored by recording the UV–vis absorption spectra for surface Plasmon resonance (SPR) peak (∼374 nm). X-ray diffraction (XRD) pattern of the ZnONPs agrees with the reported data for Zn metal and the crystallite average size is 12 nm. Scanning and transmission electron microscopic (SEM and TEM) show uniform spherical particles obtained by this green method. The antifungal activity is found to be effective of ZnONPs. Results revealed that the green synthesis is an efficient for the preparation of ZnONPs as an active antifungal agent for practical applications.
