“…Notably, the CuO NPs synthesized were spherical when using a higher concentration of sugarcane juices. In contrast, various shapes were observed from the CuO NPs synthesized with lower concentrations of sugarcane juice, ranging from spherical, square, cube, and plate shapes to a rectangular shape, along with some irregular shapes [82]. This is supported by previous studies demonstrating that increasing the concentration of plant extract when synthesizing NPs alters NP morphology, from irregular to spherical, and the size of the NPs [80].…”

“…In addition to speeding up the reaction, an increase in the concentration of plant extract also decreases the size and alters the shape of the CuO NPs formed. A recent study demonstrated that synthesizing CuO NPs using a different volume of sugarcane juice, ranging from 2-10 mL, produced CuO NPs that were 29.89-22.80 nm in size [82]. Notably, the CuO NPs synthesized were spherical when using a higher concentration of sugarcane juices.…”

“…In contrast, S. pyrogenes infects humans, causing various infections such as rheumatic fever and scarlet fever [51]. It was revealed that sugarcane-juice-mediated NPs are resistant to E. coli compared to Gram-positive bacteria B. subtilis and S. aureus [82]. However, a comparative study between Gram-negative bacteria, E. coli and P. aeruginosa, and gram-positive bacteria, S. aureus and B. cereus, with the treatment of CuO NPs synthesized using fruit extract Tribulus terrestris reported that the minimal inhibitory concentration (MIC) is higher in Grampositive bacteria compared to Gram-negative bacteria [81,86].…”

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.

“…It is well established that the Raman spectra of Cu 2 O has a peak at (308 cm −1 ) [24]. Another weak peak observed near 285 cm −1 is close to the peak normally attributed to the CuO phase [25,26]. With increase in deposition temperature, the spectra show an increase in this CuO peak compared to Cu 2 O, which is indicative of a phase conversion with annealing.…”

Copper oxide thin films are deposited on quartz substrates by DC magnetron sputtering and the effect of deposition temperature on their optoelectronic properties is examined in detail. Scanning Electron Microscopy (SEM), X-ray diffraction (XRD) analysis, Raman spectroscopy, UV-Vis spectroscopy, and four-probe sheet resistance measurements are used to characterize the surface morphology, structural, optical, and electrical properties respectively. Deposition is carried out at room temperature and between 200 and 300 °C. XRD analysis indicates that the oxide formed is primarily Cu 2 O and the absorption spectra show the films have a critical absorption edge at around 300 nm. The sheet resistance gradually decreases with increase in deposition temperature thereby increasing the conductivity of these thin films. Also observed is the increase in band gap from 2.20 eV for room temperature deposition to 2.35 eV at 300 °C. The optical band gap and the variation of sheet resistance with temperature shows that the microstructure plays a vital role in their behavior. These transformation characteristics are of huge technological importance having variety of applications including transparent solar cell fabrication.

“…There are several infectious microorganisms responsible for formation of Microbial biofilms that are sticky exopolymeric substances (EPS) causing adherence of microorganism to biotic surfaces such as host cells or abiotic surfaces such as medical devices cause antimicrobial resistance [17].Metal oxide nanoparticles are effective in fighting against multidrug resistance biofilm producing pathogenic bacteria, where CuO nanoparticles are found more effective than iron oxide and nickel nanoparticles [18], [19]. Antibacterial activity by copper and copper oxide NPs against biofilm producing organism Bacillus subtilis, Staphylococcus aureus, E. coli and Pseudomonas aeruginosa is shown [20], [21]. Effectivity of copper nanoparticles is found in varied applications such as Antifungal, Antiviral, Antibiotics, Anticancer, Photocatalytic, in biomedical, agriculture fields etc.…”

An emerging field of science “Nanotechnology” which is involved in manipulation of atoms and molecules has shown great potential in all fields of sciences. Nanotechnology deals with nanoparticles ranging from size 1 to 100 nm in diameter, due to small size and high surface area eventually increases the state of activity. This review focuses on metal and metal oxide nanoparticles and mainly on green synthesis, characterization and application of copper nanoparticles. Green synthesis of copper and copper oxide (Cu and CuO) is economically beneficial and ecofriendly. Copper nanoparticles are used in diverse fields such as biomedicine, pharmaceuticals, bioremediation, molecular biology, bioengineering, genetic engineering, dye degradation, catalysis, cosmetics and textiles. Structural properties and biological effects of copper nanoparticles have promising effectivity in field of life sciences.
