“…Additionally, CuO does not cause skin irritation, sensitisation or adverse reactions [19]. However, the most important property, which is the topic of the present work, is that CuO has antifungal and antibacterial activity for gram-positive and gramnegative bacteria [20][21][22]. Moreover, CuO nanoparticles, as antimicrobial agents, are more stable and durable than organic antimicrobial compounds [23].…”

The application of nanotechnology has gained importance in the finishing of textile products, imparting them functional properties, which are achieved without affecting the textile. A novel method was developed for the in situ growth of CuO nanoparticles (NPs) onto cotton textiles by the exhaust dyeing method. For functionalised textiles, a constant sodium hydroxide concentration (0.4 g l −1 ) and different percentages of on-weight-fabric (% owf) of copper acetate were used. The textiles were microbiologically evaluated, the laundering durability was assessed and their UV protection factor (UPF) was determined. In addition, their CIE L*a*b* colour coordinates and colour strength (K/S) were studied. The results determined that NPs on the textile were CuO and were distributed randomly on the cotton fibre surface. The functionalised textiles with CuO NPs had percentages of bacterial reduction against Escherichia coli (ATCC 25922) between 89.7 and 99.7% and showed an improvement in the UPF of cotton from approximately 7 to 32. The CuO NP content on the textile was inversely correlated with the L* value and directly correlated with the a* and b* values and the K/S parameter.

“…Research findings highlight that precursor type, proportion, and addition order impact complex formation and nanoparticle dispersion. Furthermore, Ghorbi’s suggestion to moderate the acceleration rate of silver precursors has been shown to notably improve the dispersion of silver cores in CS NPs, effectively preventing aggregation in the resulting Ag-Cu NPs; however, surpassing an optimal precursor concentration may reduce nanoparticle dispersion and lead to increased cluster formation, adversely affecting overall performance ( Ghorbi et al, 2019 ). Researchers stress the vital role of surfactants as essential stabilizers to prevent nanoparticle aggregation, while capping agents are emphasized for their potential to boost the antibacterial performance of nanoparticles and avert particle aggregation ( Manikam et al, 2011 ; Joel T and Shobini, 2018 ).…”

The excessive use of antibiotics in clinical settings has resulted in the rapid expansion, evolution, and development of bacterial and microorganism resistance. It causes a significant challenge to the medical community. Therefore, it is important to develop new antibacterial materials that could replace traditional antibiotics. With the advancements in nanotechnology, it has become evident that metallic and metal oxide nanoparticles (MeO NPs) exhibit stronger antibacterial properties than their bulk and micron-sized counterparts. The antibacterial properties of silver nanoparticles (Ag NPs) and copper nanoparticles (Cu NPs) have been extensively studied, including the release of metal ions, oxidative stress responses, damages to cell integrity, and immunostimulatory effects. However, it is crucial to consider the potential cytotoxicity and genotoxicity of Ag NPs and Cu NPs. Numerous experimental studies have demonstrated that bimetallic nanoparticles (BNPs) composed of Ag NPs and Cu NPs exhibit strong antibacterial effects while maintaining low cytotoxicity. Bimetallic nanoparticles offer an effective means to mitigate the genotoxicity associated with individual nanoparticles while considerably enhancing their antibacterial efficacy. In this paper, we presented on various synthesis methods for Ag-Cu NPs, emphasizing their synergistic effects, processes of reactive oxygen species (ROS) generation, photocatalytic properties, antibacterial mechanisms, and the factors influencing their performance. These materials have the potential to enhance efficacy, reduce toxicity, and find broader applications in combating antibiotic resistance while promoting public health.

“…The growth of microbial resistance because of the bacteria that withstand to multiple antibiotics have been remain as a part of source for the morbidity, mortality and socioeconomic loss worldwide [41]. Due to the excellent antibacterial activity of copper, the US Environmental Protection Agency had registered about 300 copper-containing products as antibacterial agent back in 2008 and they were studied for biomedical application [42], crop disease control [43] and waste water treatment [44].…”

Due to their biocidal activity properties, graphene based materials have been widely studied especially in biomedical, agriculture and water treatment process which focus on mitigating the microbial resistance problem. However, the antibacterial performance of these materials alone are relatively weak and need to be improved in order to enhance their biological activity. Copper nanoparticles is a low cost metal also has the antibacterial properties which is almost similar with the silver and gold nanoparticles. The combination of these two materials had produced to a new potential material as another alternative for the antibacterial agents. Therefore, in this work, a brief review of copper/graphene based material nanocomposites and their antibacterial study was discussed.
