“…As displayed visually in Figure 27, both MB and CR became colorless gradually after the addition of biogenic CuO in less than 2 h. They further pragmatically concluded that the decolorization, which is core visual evidence of degradation, is a function of exposure duration of the pollutant to green nanocatalyst and irradiation. [ 176 ] A very similar excellent result has been obtained by other research teams [ 140,156,160,170 ] using green CuO NPs biofabricated by employing Canthium coromandelicum leaf extract, Cardiospermum halicacabum plant extract, green tea extract, and Ocimum tenuiflorum leaf extract respectively.…”

The present scenario of water insecurity (poor availability and accessibility to clean and healthy water when needed) denotes the preponderance of environmental damage caused by effluents or waste runoff from industries, such as the dye and textile industries. The polluted waters have led to terrible and sonorous negative impacts on the ecosystem and econetworking, thus, urging for a sustainably suitable substitute to tackle and annul the noxious environmental constraint posse by the hazardous dye effluent. Several chemical and physical methods for treating dye effluent are now in use, but they are time‐consuming, expensive, and inefficient. Interestingly, nanoparticles have egressed as a superior answer for efficient dye removal and degradation, because of their chemical reactivity and exceptional surface characteristics. As a result, the use of metal nanomaterials in the treatment of dye runoffs has been thoroughly investigated. The study used major scientific databases such as SciFinder, Scopus, PubMed, Google Scholar, and Science Direct to conduct a comprehensive review of publicly available literature. Degradation, dye effluent, green metal nanoparticles, and water pollution were the keywords used to find scholarly papers. Efforts were made to figure out and explain the mechanism of dye effluent degradation, how long the degradation will take and how effective the use of plant biosynthesized metal nanoparticles for dye removal is. In addition, the role of bimetallic nanoparticles has also been investigated with remarkable feat from literature. The current level of knowledge about the mechanism and the use of plant biogenic metal nanoparticles in common dye effluent treatment is summarized in this paper.

“…They also contain active phytocompounds that serve as reducing and capping agents, such as alkaloids, terpenoids, and steroids [ 7 ]. CuONPs were successfully synthesized through green process using Enicostemma axillare leaf extract [ 8 ], Cardiospermum halicacabum leaf extract [ 9 ], and Morus alba leaf extract [ 10 ]. CuONPs produced from the endophytic fungus Aspergillus terreus showed enhanced bioactivity, including antibacterial, antioxidant, and anticancer properties [ 11 ].…”

Phytoconstituents Assisted Biofabrication of Copper Oxide Nanoparticles and Their Antiplasmodial, and Antilarval Efficacy: A Novel Approach for the Control of Parasites

The present work aimed to biofabricate copper oxide nanoparticles (CuO NPs) using Tinospora cordifolia leaf extract. The biofabricated CuO NPs were treated against the malarial parasite of chloroquine-resistant Plasmodium falciparum (INDO) and the antilarval efficacy was evaluated against the malaria vector Anopheles stephensi and dengue vector Aedes aegypti. The prominence at 285 nm in the UV–visible spectrum helped to identify the produced CuO NPs. Based on the XRD patterns, the concentric rings correspond to reflections at 38.26° (111), 44.11° (200), 64.58° (220), and 77.34° (311). These separations are indicative of CuO’s face-centered cubic (fcc) structure. The synthesized CuO NPs have FTIR spectra with band intensities of 3427, 2925, 1629, 1387, 1096, and 600 cm−1. The absorbance band at 3427 cm−1 is known to be associated with the stretching O-H due to the alcoholic group. FTIR proved that the presence of the -OH group is responsible for reducing and capping agents in the synthesis of nanoparticles (NPs). The synthesized CuO NPs were found to be polymorphic (oval, elongated, and roughly spherical) in form with a size range of 11–47 nm and an average size of 16 nm when the morphology was examined using FESEM and HRTEM. The highest antiplasmodial efficacy against the chloroquine-resistant strain of P. falciparum (INDO) was found in the synthesized CuO NPs, with LC50 values of 19.82 µg/mL, whilst HEK293 cells are the least toxic, with a CC50 value of 265.85 µg/mL, leading to a selectivity index of 13.41. However, the antiplasmodial activity of T. cordifolia leaf extract (TCLE) and copper sulfate (CS) solution showed moderate activity, with LC50 values of 52.24 and 63.88 µg/mL, respectively. The green synthesized NPs demonstrated extremely high antilarval efficacy against the larvae of An. stephensi and Ae. aegypti, with LC50 values of 4.06 and 3.69 mg/L, respectively.

“…Two the most common pathogenic bacteria, S. aureus (gram-positive) and E. coli (gram-negative), were selected for the study of the killing activity of modified wool and cotton. The antibacterial properties of copper, copper alloys and various copper compounds were studied many works [ 1 , 3 , 11 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 25 ]. Staphylococci were identified as an important cause of both nosocomial and community-acquired infections [ 16 , 21 , 28 ].…”

“…One study [ 16 ] showed that when comparing hospital waiting rooms with ordinary chairs and with chairs containing copper particles, the microbial burden in waiting rooms with the latter was reduced by 73%. In addition, the particles of copper oxides and other various copper species have been studied for their antibacterial applications [ 6 , 10 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. CuO nanoparticles are effective, non-toxic and eco-friendly interactive materials with high antibacterial activity [ 17 ]; these particles have been widely used in medical applications due to their antioxidant, antibacterial and antifungal activities [ 22 ].…”

The composition and antibacterial properties of copper particles synthesized by a very simple reduction method were studied. For the preparation of particles in knitted fabrics, copper(II) sulfate was used as a precursor and ascorbic acid as a reducing natural agent. X-ray diffraction analysis showed the crystalline nature of the obtained particles. The round or oval particles and their agglomerates in knitted fabrics consisted of copper with traces of copper(I) oxide—cuprite. The element maps and energy dispersive X-ray spectra showed a high content of copper in the samples. The samples of wool and cotton knitted fabrics with copper particles had excellent antibacterial activity against gram-positive Staphylococcus aureus (S. aureus) and gram-negative Escherichia coli (E. coli) bacterial strains. The maximum zones of inhibition were 19.3 mm for S. aureus and 18.3 mm for E. coli using wool knitted fabric and 14.7 mm and 15.3 mm using cotton knitted fabric, respectively. The obtained results showed that the modified wool and cotton fabrics are suitable for use as inserts in reusable masks due to their noticeable and long-term activity against pathogenic bacteria.
