Mono-dispersed copper nanoparticles (CuNPs) were constructed using cheap polysaccharides (citrus pectin, chitosan, and sodium alginate), and by appropriating aqueous fermented fenugreek powder (FFP) under the action of Pleurotus ostreatus (as reducing and preserving means), through the influence of gamma irradiation. The synthesized CuNPs are described by UV-Vis. spectroscopy TEM, DLS, XRD, and FT-IR. XRD study of the CuNPs confirmed the generation of metallic CuNPs. The nucleation and the production mechanism of CuNPs are moreover explained. TEM unveiled that, the ordinary diameter of CuNPs incorporated by various polysaccharides, and FFP taken in the range of 31.0 and 36.0 nm respectively. CuNPs size is influenced by many parameters such as the variety of stabilizer, pH within the organization and applied gamma dose. Evaluation of the antioxidant and antimicrobial activities of CuNPs was performed against some selected wound pathogens. The results showed that, CuNPs were a strong antimicrobial agents against microbes caused burn skin infection such as Klebsiella pneumoniae, Staphylococcus aureus, and Candida albicans (16.0, 15.0, and 15.0 mm ZOI, respectively). Additionally, CuNPs have a strong antioxidant with 70% scavenging activity against DPPH. So, due to unique characteristics of CuNPs (cost-effective with continued-term stabilization and effective features), they can recover reasonable potential in biomedical, industrial, agricultural, cosmetics, dermal products and pharmaceutical purposes.
