The use of plant extract in the biosynthesis of nanoparticles (NPs) can be an eco-friendly approach and have been suggested as a possible alternative to classic methods namely physical and chemical procedures. In this study, the biosynthesis of @entity1947 ( @entity1948 ) NPs by both "conventional heating" ( @entity7617 ) and "microwave irradiation" ( @entity7841 ) methods has been reported. Stable and spherical ZnONPs were produced using @entity57566 and flesh extract of Rosa canina fruit (rosehip) which was used as a precursor. The flesh extract acts as a reducing and capping agent for generation of ZnONPs. The structural, morphological and colloidal properties of the as-synthesized NPs have been confirmed by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), Fourier transform Infrared (FT-IR) and Dynamic Light Scattering (DLS). In comparison with the @entity7617 method, the @entity7841 method has some advantages such as significantly short reaction time (within 8min) owing to the high heating rate and thus the accelerated reaction rate. Both methods led to the synthesis of nearly identical NPs with respect to shape and size according to the results of DLS, XRD and SEM techniques. The possible mechanism for synthesis pathway has been proposed based on FT IR results, XRD patterns, potentiometric data and antioxidant activity. In addition, the antibacterial activity of as-prepared ZnONPs was investigated against several bacteria such as @entity5125 , @entity526 , @entity2491 . Moreover, the efficacy of ZnONPs to treat @entity5 cell lines were measured by means of cell viability test via @entity98 assay in which concentrations of 0.05 and 0.1mg/mL of ZnONPs induced a very low @entity137 . Thus, the present investigation reveals that ZnONPs have the potential for various medical and industrial applications.
