“…Bands indicating this behavior are observed at 1506, 1409, 1176, 850, and 793 cm −1 , characteristic of phenolic compounds, a band at 1117 cm − , characteristic of proteins, a band at 1472 cm −1 , characteristic of lipids, and a band at 874 cm -1 , attributed to the presence of glucose, possibly due to the interaction of these phytochemicals with the Cu2O-NPs [53]. Another band close to 1717 cm −1 is attributed to the presence of C=O bonds, possibly arising from the oxidation of -OH groups to C=O during the reduction of Cu 2+ ions to Cu + for the subsequent formation of Cu2O [54].…”

Water pollution, particularly from organic contaminants like dyes, is a pressing issue, prompting exploration into advanced oxidation processes (AOPs) as potential solutions. This study focuses on synthesizing Cu2O on cellulose-based fabric using Eucalyptus globulus leaf extracts. The resulting catalysts effectively degraded methylene blue through photocatalysis under LED visible light and heterogeneous Fenton-like reactions with H2O2, demonstrating reusability. Mechanistic insights were gained through analyses of the extracts before and after Cu2O synthesis, revealing the role of phenolic compounds and reducing sugars in nanoparticle formation. Cu2O nanoparticles on cellulose-based fabric were characterized in terms of their morphology, structure, and bandgap via SEM-EDS, XRD, Raman, FTIR, UV–Vis DRS, and TGA. The degradation of methylene blue was pH-dependent; photocatalysis was more efficient at neutral pH due to hydroxyl and superoxide radical production, while Fenton-like reactions showed greater efficiency at acidic pH, primarily generating hydroxyl radicals. Cu2O used in Fenton-like reactions exhibited lower reusability compared to photocatalysis, suggesting deterioration. This research not only advances understanding of catalytic processes but also holds promise for sustainable water treatment solutions, contributing to environmental protection and resource conservation.

“…Similarly, there are few reports about the biological synthesis of CuO NPs using different fungal extracts such as Trichoderma asperellum , Aspergillus terreus , Trichoderma harzianum , and Stereum hirsutum (Consolo et al 2020 ; Cuevas et al 2015 ; Mani et al 2021 ; Saravanakumar et al 2019 ). Additionally, Bhattacharya et al ( 2019 ), Araya-Castro et al ( 2021 ), and Taherzadeh Soureshjani et al ( 2021 ) documented algae-mediated synthesis of CuO NPs using different algal species including Anabaena cylindrica , Macrocystis pyrifera , Cystoseira myrica , Sargassum latifolium , and Padina australis.…”

Versatile nature of copper oxide nanoparticles (CuO NPs) has made them an imperative nanomaterial being employed in nanomedicine. Various physical, chemical, and biological methodologies are in use for the preparation of CuO NPs. The physicochemical and biological properties of CuO NPs are primarily affected by their method of fabrication; therefore, selectivity of a synthetic technique is immensely important that makes these NPs appropriate for a specific biomedical application. The deliberate use of CuO NPs in biomedicine questions their biocompatible nature. For this reason, the present review has been designed to focus on the approaches employed for the synthesis of CuO NPs; their biomedical applications highlighting antimicrobial, anticancer, and antioxidant studies; and most importantly, the in vitro and in vivo toxicity associated with these NPs. This comprehensive overview of CuO NPs is unique and novel as it emphasizes on biomedical applications of CuO NPs along with its toxicological assessments which would be useful in providing core knowledge to researchers working in these domains for planning and conducting futuristic studies. Key Points • The recent methods for fabrication of CuO nanoparticles have been discussed with emphasis on green synthesis methods for different biomedical approaches. • Antibacterial, antioxidant, anticancer, antiparasitic, antidiabetic, and antiviral properties of CuO nanoparticles have been explained. • In vitro and in vivo toxicological studies of CuO nanoparticles exploited along with their respective mechanisms.

“…It was discovered that produced nanoparticles had antibacterial action against Gram-positive bacteria (Staphylococcus aureus) and Gram-negative bacteria (Pseudomonas aeruginosa and Escherichia coli). Furthermore, when tested on a human leukaemia cell line, the Cu 2 O NPs demonstrated excellent anticancer activity (K562) [62].…”

In recent era, green trend of synthesising biogenic nanoparticles (NPs) is a sustainable, safe, environment-friendly, and relatively inexpensive substitute to conservative routes of NPs making. Biosynthesis route showcases significant properties such as the absence of poisonous chemical compounds used as stabilising or reducing agents, lack of toxic yields generated from the process, reduced energy consumption, inexpensiveness, and high scalability. This has made green synthesis methods more attractive than other traditional methods. Synthesis of nanomaterials (NMs) using algae extracts is a substantiating ecological, simple, low-priced biosynthesis process. The secondary metabolites from algae have been reported to reduce metal precursors to nanoparticles (metal, metal oxide, or bimetallic NPs). Moreover, they cap and stabilise. Depending on the site of NP formation, synthesis could occur intra or extra-cellularly. Among the varied series of algae mediated synthesis, the most commonly biosynthesised NPs are silver, gold, copper oxide, cuprous oxide and zinc oxide. The algal biosynthesised NPs have been reviewed for numerous biomedical applications, which comprise anti-cancerous, anti-fouling, anti-bacterial, anti-fungal, bioremediation, and biosensing activities. The current review draws the major stress on the basis behind the algal-mediated biosynthesis of metallic and metallic oxide NPs from various algae. Furthermore, special attention to critical understanding of biosynthesis mechanism of NPs from algae and their biomedical applications has been reviewed critically.
