Characterization, biosynthesis of copper nanoparticles using ginger roots extract and investigation of its antibacterial activity

Abstract

The emergence of antibiotic resistance of bacteria, fungi, and viruses recently, which led to the interest in developing antimicrobial agents and making them more effective in the fields of sterilization, public health, food preservation, etc., which led to the adoption of mineral elements as antimicrobials. Bacterial and antiviral agents. Nickel and copper are among the options that include antimicrobial because they are corrosion resistant and strong. Copper was recognized by the US Environmental Protection Agency (EPA) in 2008 as an antimicrobial as the first metallic agent. In this work, the green method successfully synthesized copper nanoparticles from ginger extract within a short period and the samples were examined using multiple analytical techniques such as scanning field emission electron microscopy (FE-SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and energy-dispersive X-ray (EDX) analysis to study its structure and morphology. Then it was used as an antibacterial. Here, tests were performed on two pathogenic strains of Gram-negative (G−ve) and Gram-positive (G+ve) bacteria, Staphylococcus aureus, and Escherichia coli. At 37 °C, copper showed a response to inhibition of the action of these two strains during 24 h of incubation. Although copper is improved, this method can be extended to other types of metallic surfaces and other bacterial strains.
