Nanoparticles (NPs) have already been widely used in catalysis, antibacterial and coating fields. Compared with the traditional toxic and harmful reducing reagents, green synthesis of NPs by using plant extracts is not only environmental-friendly and cost-effective but also conducive to the multi-level and efficient utilization of wild plant resources. In this study, the aqueous extracts from Sorbus pohuashanensis (SP) and Aronia melanocarpa (AM) fruits were used as the reducing and protective reagents for synthesizing Au/AgNPs, with the characteristics of originality operation and high repeatability. The SP/AM fruit extracts functionalized Au/AgNPs were characterized by UV-vis spectroscopy (UV-vis), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), scanning electron microscope (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). UV-vis spectrums showed the NPs peaks verified by the presence between 400–550 nm; TEM and SEM demonstrated NPs displayed approximately spherical structures; EDS confirmed the existence of Au/Ag elements; XRD measurements confirmed that the obtained NPs showed highly crystalline structures; FTIR demonstrated the fruits extracts were adsorbed on the surface of NPs. Primary experiments indicated that SP/AM fruit extracts functionalized-NPs could be used as the reagents for removing the organic dyes efficiently; Zone of inhibition tests (ZOI) explained that NPs have slow-release antibacterial activity.
