“…e resulting NPs exhibited spherical or elongated shapes with a diameter of 13 nm; however, in this work, the major limitation is the use of fungi as a bio-reducing, stabilizing, and capping agent, since they must shake at 150 rpm for two days [12]. As another method, Arunkumar et al conducted experiments using sterile distilled water to treat Lantana camara leaf extracts in order to obtain CuO NPs using CuCl 2 .2H 2 O as a salt precursor, NaOH, and sterile distilled water as the plant treatment solution.…”

“…Based on characterization studies, it has been demonstrated that when nanocomposites with high copper contents are synthesized, the crystallinity index of cellulose is modified based on the reaction conditions, and the chemical structure of cellulose is destroyed. Using UV spectroscopy in the 300-350 nm range, CuO NPs was confirmed to be the by-product of the reaction [12].…”

The propolis produced by bees is used by them to protect their hives. The cavity inside the hive’s walls is filled in during cold days to reduce entry points and mummify any intruders to ensure their survival. A current focus in nanotechnology and nanoscience is the green biosynthesis of nanoparticles (NPs) using biomaterials. Research on green methods for making metal oxide NPs is gaining momentum to safeguard the environment from the potential dangers associated with toxic chemicals. This study aimed to synthesize copper NPs (CuNPs) via propolis extraction, a novel application of nanoscience. The study was conducted under a range of pH, time conditions, and concentration ratios, and its properties were characterized by UV-Vis absorption spectra, XRD, and FTIR. An FTIR analysis revealed that compounds found in propolis extract could have an effect on the surface modification of the synthesized NPs. The propolis (Khalkhal) extract spectrum exhibited a sharp peak at 3422 cm−1, caused by free hydroxyl groups and their intra/intermolecular hydrogen bonds. There were sharp peaks at 2925, 1637, and 1515 to 1076 cm−1 associated with the C = O and C = C aromatic stretching frequencies. According to UV-Vis spectrophotometry investigation, CuO NPs exhibit a characteristic peak at 385 nm, showing significant surface plasmon resonance (SPR) with propolis (Khalkhal) extract. Furthermore, specific wavelengths of CuO NPs demonstrate peaks at 243, 292, and 350 nm for propolis (Gilan) extract. The green synthesis of CuNPs from Gilan and Khalkhal propolis can be an appropriate candidate for clinical applications such as drug delivery systems, drug formulation, and biomedical applications.

“…Among all the described methods, chemical wet processing is considered the simplest, most effective, and most suitable for the saturation of textile materials with copper-containing particles [ 38 ]. This process includes the reduction of copper cations in solutions of copper salts with a reducing agent to a metal with zero valency followed by blocking and stabilization of nanoparticles in textile materials of cellulosic origin [ 39 , 40 , 41 ] or non-woven polypropylene fabrics [ 42 ]. Thus, in view of the above, imparting antibacterial and antiviral properties to textile materials in a simple, environmentally friendly, easily controlled, fast, and energy-efficient method that can play a significant role in preventing the spread of airborne viruses, including SARS-CoV-2, in the current stressful situation caused by the pandemic.…”

Textile materials modified with copper-containing particles have antibacterial and antiviral properties that have prospects for use in healthcare. In the study, textile materials were saturated with copper-containing particles in their entire material volume by the absorption/diffusion method. The antibacterial properties of modified textile materials were confirmed by their inhibitory effect on Staphylococcus aureus, a Gram-positive bacterium that spreads predominantly through the respiratory tract. For the modification, ordinary textile materials of various origins and fiber structures were used. Technological conditions and compositions of modifying solutions were established, as well as the most suitable textile materials for modification. To assess the morphological and physical characteristics of copper-containing particles and the textile materials themselves, X-ray diffraction, a scanning electron microscope, and an energy-dispersive X-ray spectrum were used. In modified textile samples, XRD data showed the presence of crystalline phases of copper (Cu) and copper (I) oxide (Cu2O). On the grounds of the SEM/EDS analysis, the saturation of textile materials with copper-containing particles depends on the structure of the textile materials and the origins of the fibers included in their composition, as well as the modification conditions and the copper precursor.

“…The green synthesis method is environmentally friendly, since the chemical reduction agents are replaced by nontoxic natural compounds [ 16 ]. An example of this green route is the synthesis of Cu NPs in the presence of cotton without the addition of chemical reducing agents, which exclusively produces oxidation-stable Cu NPs in a facile manner [ 18 ]. On the other hand, the method of chemical reduction in an aqueous medium is one of the most widely used for Cu NPs synthesis due to the water’s capability to dissolve a wide variety of metallic salts and the method’s reproducibility [ 19 , 20 ].…”

In this work, we report the synthesis of copper nanoparticles (Cu NPs), employing the chemical reduction method in an aqueous medium. We used copper sulfate pentahydrate (CuSO4·5H2O) as a metallic precursor; polyethylenimine (PEI), allylamine (AAM), and 4-aminobutyric acid (AABT) as stabilizing agents; and hydrated hydrazine as a reducing agent. The characterization of the obtained nanoparticles consisted of X-ray, TEM, FTIR, and TGA analyses. Through these techniques, it was possible to detect the presence of the used stabilizing agents on the surface of the NPs. Finally, a zeta potential analysis was performed to differentiate the stability of the nanoparticles with a different type of stabilizing agent, from which it was determined that the most stable nanoparticles were the Cu NPs synthesized in the presence of the PEI/AAM mixture. The antimicrobial activity of Cu/PEI/AABT toward P. aeruginosa and S. aureus bacteria was high, inhibiting both bacteria with low contact times and copper concentrations of 50–200 ppm. The synthesis method allowed us to obtain Cu NPs free of oxides, stable to oxidation, and with high yields. The newly functionalized Cu NPs are potential candidates for antimicrobial applications.
