Reversible Formation

CO2 sensing at room temperature: the interaction of CO2 and H2O with copper oxide nanoparticles results in reversible formation of basic carbonates. This phenomenon is the key reaction for the work function readout based CO2 sensing which enables the prospects towards low power and low cost gas sensors.

The aim of present study is based on low cost, efficient, non-toxic and eco-friendly method for green synthesis of copper oxide nanoparticles (CuONPs) using Bougainvillea leaves aqueous extract. The green synthesized nanoparticles were subjected to characterization techniques UV–visible spectroscopy (UV–vis), X-ray diffraction (XRD), Fourier transform Infrared spectroscopy (FT-IR) and transmission electron microscope (TEM). The synthesized CuONPs were pure, predominantly spherical with sizes ranges from 8-20 nm. CuONPs showed excellent antimicrobial activity against various bacterial strains Escherichia coli, Enterococcus faecalis, and Staphylococcus aureus. Moreover, E. coli and E. faecalis exhibited the highest sensitivity to CuONPs while Staphylococcus aureus was the least sensitive. Possible mechanisms of antimicrobial activity of CuONPs should be further investigated.

Reducing Properties

Plants are rich in phytoconstituent biomolecules that served as a good source of medicine. More recently, they have been employed in synthesizing metal/metal oxide nanoparticles (NPs) due to their capping and reducing properties. This green synthesis approach is environmentally friendly and allows the production of the desired NPs in different sizes and shapes by manipulating parameters during the synthesis process. The most commonly used metals and oxides are gold (Au), silver (Ag), and copper (Cu). Among these, Cu is a relatively low-cost metal that is more cost-effective than Au and Ag. In this review, we present an overview and current update of plant-mediated Cu/copper oxide (CuO) NPs, including their synthesis, medicinal applications, and mechanisms. Furthermore, the toxic effects of these NPs and their efficacy compared to commercial NPs are reviewed. This review provides an insight into the potential of developing plant-based Cu/CuO NPs as a therapeutic agent for various diseases in the future.

Disk Diffusion Assay

Fifty specimens were collected from wound patients who visited Al-Hilla Teaching Hospital. The samples were grown on Blood and MacConkey agar for 24-48 hr at 37oC. The bacterial isolates which achieved as a pure and predominant growth from clinical samples as Pseudomonas fluorescens, were identified using morphological properties and Vitek2 system. The anti-bacterial activity of copper oxide nanoparticles (CuO NPs) against was tested by (disk diffusion assay) using dilutions of (400, 200, 100, 50, 25, and 12.5‎µ‎g/ml). The (MIC and MBC) of each isolate was determined. CuO NPs shows wide spectrum antibacterial activity against tested bacteria with rise zone of inhibition diameter that is proportionate with the increase in nanoparticle concentration. The MIC of CuO NPs extended from 100-200‎µ‎g/ml and the MBC ranged from 200-400‎µ‎g/ml. The antibiotic profile was determined by Viteck 2 compact system (Biomérieux). CuO NPs‎ found highly effective and safe in P. fluorescens wounds infections comparing with used antibiotics.

Effective Use

In material science, green method for synthesis of nanomaterials is feasible, cheaper and eco-friendly protocol. To accomplish this phenomenon, present study was aimed to synthesize Copper oxide nanoparticles using leaf extract of Aloevera with two different precursors CuCl2.2H2O (Cupric chloride) and CuSo4.5H2O (Cupric sulfate). The extraction of Aloevera is employed as reducing and stabilizing agent for this synthesis.Copper oxide Nanoparticles is effective use of biomedical application due to their antibacterial function. The synthesized Copper oxide nanoparticles were characterized by X-Ray Diffraction Spectroscopy (XRD), Energy Dispersive Spectroscopy (EDX), FourierTransform Infrared Spectroscopy (FT- IR) and Scanning Electron Microscope(SEM). XRD studies reveal the crystallographic nature of Copper oxide nanoparticles. Furthermore the Copper oxide nanoparticles have good Antibacterial activity against both gram negative (E.Coli, Klebsiella pneumonia) and gram positive (Bacillus cereus, Staphylococcus aureus)bacteria.
