Abstract :Objective: Silver nanoparticles insert ignore into journalissuearticles values(AgNPs); have a wide range of applications. Environmental-friendly synthesis methods for these nanoparticles are more preferable due to their various advantages. This study aimed to synthesize AgNPs using the extract of the tomato plant in an easy and economical way. and testing this AgNPs against some human pathogens. Methods: Silver nanoparticles were synthesized using aqueous silver nitrate and reducing tomato plant extract. The characterization of AgNPs was determined by ultraviolet-visible spectrophotometry insert ignore into journalissuearticles values(UV-Vis);, X-ray crystallography insert ignore into journalissuearticles values(XRD); Scanning electron microscopy insert ignore into journalissuearticles values(SEM);, Fourier transform infrared Spectroscopy insert ignore into journalissuearticles values(FT-IR);, energy dispersive X-ray spectrum insert ignore into journalissuearticles values(EDAX);, thermogravimetric - differential thermal analysis insert ignore into journalissuearticles values(TGA-DTA); data. The effects of the particles on pathogenic microorganisms were determined by minimum inhibition concentration insert ignore into journalissuearticles values(MIC);. Results: These data, with a maximum absorbance of 450.51 nm, in the spherical view, with the peaks and values of 111 o , 200 o , 220 o and 311 o insert ignore into journalissuearticles values(38.08, 44.28, 64.42 and 77.34);, AgNPs showed a cubic crystal structure and, using the Debye-Scherrer equation, it was determined that they had a crystal size of 21.11 nm AgNPs had an antimicrobial activity on hospital pathogens gram negative, gram positive and Candida albicans yeast. Conclusion: We found that these particles showed antimicrobial activity on various microorganisms even at very high concentrations. As a solution to the antimicrobial search, it can be developed in medical industry.
