Preparation of molybdenum nanoparticles using cold plasma as antibacterial

Abstract

In this paper, molybdenum nanoparticles (Mo NPs) were prepared by cold plasma method with different concentrations and time constant. Some structural tests were performed using X-ray diffraction (XRD). and field emission scanning electron microscopy (FESEM). and energy-dispersive X-ray spectroscopy (EDX). Average crystal size is variable. Effect of the prepared nanomaterial on the growth of Pseudomonas aeruginosa bacteria. The results of those tests showed that the prepared substance at concentrations of (1.5 and 2) mM when exposed to plasma (12 min). As the results of their assays showed the polycrystalline structure of all samples of the cubic structure, the results also showed that the average crystal size changes directly with the change of concentration. On the other hand, the results of this research showed that Gram-negative bacteria (Pseudomonas aeruginosa) were resistant to Mo NPs prepared at a concentration of (1.5 and 2) mM at dilutions (0.5, 2, 4, 8, 16, 32). ). But at dilution 64, there was little inhibition of its growth.
