A facile, fast and inexpensive method to preparation of silver nanoparticles (CME@Ag-NPs) with very favorable efficiency in biological assay has been expanded utilizing Crataegus microphylla fruit extract as reducing agent. Some parameters such as pH, time, AgNO₃ concentration and temperature on the biological assay efficiency and morphological characteristics of CME@Ag-NPs were investigated to reach optimum condition. FT-IR, XRD, TEM, DLS, FESEM, EDS and UV/Vis analysis were used to investigate the properties of the as-synthesized CME@Ag-NPs. Regular, homogeneous and spherical-like morphology of CME@Ag-NPs with a mean particle size of 30–50 nm was obtained from FESEM and TEM images. The antibacterial activity of CME@Ag-NPs was explored on Acinetobacter baumannii, Staphylococcus aureus, Enterococcus, Pseudomonas, Escherichia coli, Klebsiella and Proteus mirabilis bacteria by MIC and MBC test. Investigation of the antibacterial activity showed that as-obtained nanoparticles have significant activity against Proteus mirabilis (MIC value of 3.5 μg/ml and MBC value of 7 μg/ml) than other bacterial strains. Further, antibacterial activity of CME@Ag-NPs was determined against multidrug-resistant. Interestingly, as-synthesized silver nanoparticles displayed considerable antibacterial activity against all the test strains. In vitro cytotoxicity of nanoparticles on MCF-7 and AGS cell lines was assayed in different concentration of CME@Ag-NPs and doxorubicin as positive control. As the results show, CME@Ag-NPs is excellent effective in inhibiting the growth of MCF-7 and AGS cell lines.
