Nano-AgO particle synthesis and characterization by chemical reduction and antimicrobial activity against Gram-positive and Gram-negative bacteria.
In this study, nano-AgO particles were synthesized through the chemical reduction method. The nano-AgO particles produced exhibit a bactericidal effect due to their increased reactivity stemming from a high surface-to-volume ratio. We looked at the structure and shape of nano-AgO particles, which are known to be very harmful to both types of bacteria, including those that are resistant to antibiotics. The created nano-AgO particles were carefully studied using different methods, including Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and X-ray Diffraction Spectroscopy (XRD). The results showed that the nano-AgO particles are clumps of tiny particles that are mostly between 100 to 200 nm in size. The tests showed that nano-AgO particles were effective in killing bacteria such as P. aeruginosa, S. pyogenes, and Klebsiella pneumoniae, creating a 17 mm zone where bacteria could not grow.
