Antimicrobial and Antibiofilm Activity of Silver Nanoparticles Biosynthesized by Mentha Spicata Aqueous Leaves Extract Against a. Baumannii

Abstract

Silver nanoparticles (AgNPs) have been used as antibacterial and anti-biofilm due to their different physical, chemical, and biological characteristics. Investigating silver nanoparticles' antibacterial and anti-biofilm properties was the objective of the current study. Here, we show a rapid, reliable, cost-effective, and green method for the the synthesis of AgNPs by treating silver ions with Mentha spicata aqueous leaves extract. Using the disc diffusion test, the antibacterial and anti-biofilm activities AgNPs, biofilm inhibition, in A. baumannii. Our results indicate that nanoparticles have spherical shapes and sizes.Dilutions of AgNPs (240, 120 and 60g/ml) were made. Bacteria have activated in nutrient broth for 24 hours at 37°C. The results of the study also show the effective effect of AgNPs anti-biofilm for its ability to inhibit bacterial membranes. Finally, green nanoparticles might some future function as affordable antibiotic alternatives.
