Green synthesis of copper nanoparticles using artemisia plant extract

Abstract

Nanoparticles are now attracting a lot of attention due to their tiny size and amazing characteristics including high surface area, cost-effectiveness, and readily rotatable morphology and form. Plant-based nanoparticle production is not only environmentally benign, but also inexpensive and simple. The Artemisia plant was utilised to synthesise in our research (Cu NPs). Nano copper was characterised using a UV–visible spectrophotometer, FTIR (Fourier Transform Infrared) spectroscopic study, XRD, SEM, and EDX. Cu NPs had a maximum absorbance of 405 nm, whereas SEM micrographs revealed spherical shaped Cu particles with an average size of 38.5 nm. The existence of polyphenols in Artemisia leaf extract was verified by FTIR spectra, and a spectral band at 1623 cm−1 is a hallmark of copper-extract interaction. The crystalline appearance of (Cu NPs) in nature was verified by XRD analysis. The antibacterial research was conducted on E. coli and Bacillus subtilis, and a good zone of inhibition was seen at 20.5 and 26.7 mm, respectively, demonstrating Cu NPs' potential as a treatment for infectious illnesses.
