Rationale: Nanotechnology is the study of manipulation of material at nanoscale. At nanoscale particles exhibit unique properties like, sensor, catalytic, and antibacterial. Copper Nanoparticles (Cu-NPs) were synthesized using Brassica oleracea L. (Cabbage) extract in the current examination through an ecological green and straightforward method.

Copper Nanoparticles (Cu-NPs) were synthesized using Brassica oleracea L. (Cabbage) extract in the current examination through an ecological green and straightforward method.
Results: temperature, time, concentration, and pH, A UV-visible spectrophotometer confirmed the formation of copper nanoparticles. Obtained spectra showed the absorption peak at 550 nm. UV-visible spectrophotometer, Energy Dispersive X-Ray spectroscopy (EDX), Fourier infrared spectroscopy (FTIR), and Scanning Electron Microscopy (SEM) was utilized to characterize the produced Cu-NPs. SEM results showed the synthesized Cu-NPs have an average size and shape. FTIR results committed the existence of functional groups at different positions. EDX spectra showed the elemental composition of extract and synthesized Cu- NPs. The biosynthesized Cu-NPs is also used as an antibacterial agent against selected pathogens like Escherichia coli, Gram-negative Pseudomonas spp, and Bacillus spp.
Discussion: The biosynthesized Cu-NPs used as a catalyst in the reduction of 4-nitrophenol into 4-aminophenol by utilizing sodium borohydride in a liquid solution and showed tremendous results. Results revealed that the Brassica oleracea L. (cabbage) extract is effective for the synthesis of copper nanoparticles and biosynthesized copper nanoparticles used as an antibacterial agent for Bacillus spp. and a catalyst in the organic transformation of 4-Nitrophenol.
