The antibacterial properties of these bioengineered Cu nanoparticles were tested toward a Gram-positive bacteria – Staphylococcus aureus – and two strains of Gram-negative bacteria – Escherichia coli and Pseudomonas putida. The infrared spectra detected organic bioactive molecules associated with capping and stabilization of the particle surface. High-resolution transmission electron microscopy was done to obtain information about the morphology and microstructure of the green nanoparticles. The pattern of X-ray diffraction revealed the crystallinity and different phases of the nanoparticles. The stability and gradual formation of copper nanoparticles during interaction with the extract were investigated using ultraviolet-visible spectroscopy. Here, we report on the novel green synthesis of metallic copper nanoparticles from copper sulfate solution by using the leaf extract of Heliconia psittacorum. ![]()
