“…Although both elements have remarkable antimicrobial properties, as shown in numerous studies [29,[32][33][34][35], to our best knowledge, we have not found any study to discuss the antimicrobial activity of Cu-Au NPs. The biocide activity of metal NPs is well known and occurs with different intensities depending on the synthesis procedure, concentration, dimensions, and the shape of the NPs, but their action mechanism is not fully understood [24,36,37].…”

“…Recently, research was conducted to develop different Au-based metal alloy nanoparticle systems (e.g., Au-Ag, Au-Pd, Au-Pt) [6], among which Cu-Au-based systems have aroused high interest for various applications in catalysis (CO 2 and p-nitrophenol reduction, methanol, and CO oxidation [6]), photonics (sensors for the detection of persistent toxic organic pollutants [26]), or biomedical research (photothermal therapy [27]). The alloying of copper with gold is an effective method to reduce the gold costs and to improve the stability of copper, while benefiting from their individual properties: Au is a biocompatible element with high stability, size-tunable surface plasmon resonance, fluorescence, and easy-surface functionalization [28], and copper has unique catalytic and optical properties [29][30][31].…”

The use of nanotechnologies in the applied biomedical sciences can offer a new way to treat infections and disinfect surfaces, materials, and products contaminated with various types of viruses, bacteria, and fungi. The Cu-Au nanoparticles (NPs) were obtained by an eco-friendly method that allowed the obtaining in a one-step process of size controlled, well dispersed, fully reduced, highly stable NPs at very mild conditions, using high energy ionizing radiations. The gamma irradiation was performed in an aqueous system of Cu2+/Au3+/Sodium Dodecyl Sulfate (SDS)/Ethylene Glycol. After irradiation, the change of color to ruby-red was the first indicator for the formation of NPs. Moreover, the UV-Vis spectra showed a maximum absorption peak between 524 and 540 nm, depending on the copper amount. The Cu-Au NPs presented nearly spherical shapes, sizes between 20 and 90 nm, and a zeta potential of about −44 mV indicating a good electrostatic stability. The biocidal properties performed according to various standards applied in the medical area, in dirty conditions, showed a 5 lg reduction for Staphylococcus aureus, Pseudomonas aeruginosa, and Enterococcus hirae, a 5 lg reduction for both enveloped and non-enveloped viruses such as Adenovirus type 5, Murine Norovirus, and human Coronavirus 229E, and a 4 lg reduction for Candida albicans, respectively. Thus, the radiochemically synthesized Cu-Au alloy NPs proved to have high biocide efficiency against the tested bacteria, fungi, and viruses (both encapsulated and non-encapsulated). Therefore, these nanoparticle solutions are suitable to be used as disinfectants in the decontamination of hospital surfaces or public areas characterized by high levels of microbiological contamination.

Aspergillus parasiticus (A. parasiticus) is known for producing aflatoxins and is a major threat to the food industry. Green synthesis of nanoparticles (NPs) is a cost-effective and environment-friendly approach. A variety of NPs have been explored as antifungal agents; however, their antifungal characteristics need to be further enhanced to compete with traditional fungicides. The present work describes the green synthesis of ZnO and CuO NPs by precipitation method using aqueous leaf extract of Manilkara zapota and their surface modification through polyaniline (PANI). Still, there is no published study on the application of PANI-coated particles as antifungal agents against A. parasiticus and hence was the focus of this work. The polymer-coated NPs were synthesized, characterized, and investigated for their antifungal properties against A. parasiticus. Textural and structural characterization of PANI-coated and non-coated ZnO and CuO NPs were confirmed through FT-IR, SEM, and XRD techniques. The PANI-coated NPs presented higher fungal growth inhibition (%) as compared to the non-coated ones. The maximum inhibition of 77 ± 2% (n = 3) was shown by PANI/ZnO NPs at a concentration of 12 mmol L−1 and 72 h of incubation. The non-coated NPs presented a lower inhibition rate with respect to their coated NPs, thus justifying the role of polymeric coating in improving antifungal efficiency.

Over the last few decades, several studies have been undertaken to determine the benefits and drawbacks of various copper nanoparticle synthesis processes. Copper nanoparticles have garnered considerable attention because of their remarkable optical and electrical properties. CuNPs' optical, electrical and chemical characteristics are substantially depending on their synthesis procedures. Copper is less expensive than precious metals such as gold and silver, and it also possesses strong photocatalytic and antimicrobial competencies.In this review, synthesis of copper nanoparticles by various methods such as physical, chemical and biological is elaborately illustrated and in the meantime it's also explained how different reaction variables like temperature, pressure, reaction time, and reactor properties affect the size, shape, and surface area of produced copper nanoparticles. Moreover, photocatalysis and antibacterial mechanism for copper nanoparticles are also illustrated with proper illustration.
