In the field of health, silver nanoparticles are used to make detergents. Considering the negative environmental problems in the conventional methods of synthesizing silver nanoparticles, this experimental study was conducted with the aim of using an environmentally friendly method for the production of silver in the form of antimicrobial nanoparticles and its application in detergent production.

In this research, in order to synthesize silver nanoparticles, the method of electrical explosion of wire and PNC device was used in distilled water solution as a plasma medium. Size, structural properties and morphology were investigated by X-ray diffraction (XRD), Infrared spectroscopy (FTIR), atomic force microscopy (AFM) and scanning electron microscopy (SEM), respectively. To prepare the detergent, the method selected by various pre-tests, which had the best result, was used and the antimicrobial activity test was finally performed.

The results obtained using microscopic methods showed that the nanosized silver particles were spherical and had a mean particle size of 40 nm and remained stable in distilled water solution. The results of the antimicrobial test showed that the detergent containing silver nanoparticles had the highest and lowest antimicrobial activity against staphylococcal coagulase and colonic bacteria, respectively.

Based on the results, electrical wire explosion is an appropriate and environmentally friendly method for producing silver nanoparticles. The detergent production using synthetic silver nanoparticles, along with its antimicrobial properties, is a good advancement in health and medicine.
