“…The varied results of synthesized NPs can be the result of the quality of commercially available NP colloids, human mistakes during the synthesis, and the conditions of this process, according to AgCuNPs. Studies carried out by Paszkiewicz et al [30] suggest that the methods of NP synthesis influence the average size of NPs. In their studies, the average size of AgNPs was 40 nm using NaBH4, and was even 10 times lower in comparison to NPs received using N 2 H 4 reducing agent [30].…”

Nowadays, mastitis is one of the biggest problems in breeding dairy cattle. Treatment of this disease with conventional antibiotics is ineffective because many pathogens are resistant. Researchers have therefore been forced to look for new solutions, and metal nanoparticles (NPs) have been found to be the most appropriate agents. This study uses commercially available silver (AgNPs) and copper (CuNPs) nanoparticles and synthetized silver–copper nanoparticles (AgCuNPs) to evaluate the effect of these NPs on human and bovine mammary cells. The effect of AgNPs, CuNPs, and AgCuNPs on pathogen species commonly involved in udder inflammation (e.g., Staphylococcus aureus and Escherichia coli) was also established. The results show that commercially available NPs were of good quality and did not have a toxic effect on mammary gland tissue. AgNPs, CuNPs, and AgCuNPs also influenced or decreased the viability of pathogens. Therefore, the presented data suggest that metal NPs could be used in mastitis prevention and treatment in the future. However, the presented preliminary results require further in vivo analysis.

“…The difference between the values obtained is associated with the exchange of ligands that occurs when functionalizing the AgNPs with folic acid. Additionally, the AgNPs in this range of values observed are considered to be stable [49]. The negative charge on the surface of the nanoparticles could be associated with the presence of the deprotonated carboxyl groups of folic acid [31,59].…”

Herein, we report the synthesis of silver nanoparticles (AgNPs) using direct micelles and reverse micelles of sodium bis (2-ethylhexyl) sulfosuccinate (AOT) as reaction media. We evaluated the effect of these self-organized aggregates in the nucleation and growth mechanism of AgNPs. The results show the effect of water when it is a confined medium, where their properties are different from those of net water. These factors strongly influence the size, polydispersity and shape of nanoparticles. Moreover, the presence of ions from the reducing agents and the surfactant, it is a key factor in the anisotropy of the AgNPs obtained. For our knowledge, this is the first report in which the effect of the reaction media is evaluated by using direct and reverse micelles to synthesize silver nanoparticles. Additionally, AgNPs synthesized through the two systems were functionalized with folic acid and evaluated their cytotoxicity and photothermal properties. The results show that AgNPs synthesized through the two systems are potential photothermal agents, reaching to reduce up to 47% of the viability of the HeLa cells, using a laser of 808 nm.

“…In view of this, we recently obtained and characterized a series of colloidal solutions to impregnate fabrics that will exhibit antibacterial and antifungal properties [69]. In this work we show the application of selected five types of impregnation solutions, containing Ag/Cu in the form of bimetallic nanoparticles (alloy and core-shell) as well as ionic species, for textiles impregnation.…”

We reported a preparation and characterization of five kinds of impregnation solutions, containing Ag/Cu in the form of bimetallic nanoparticles (alloy and core-shell) as well as ionic species. The cotton-polyester textiles were successfully impregnated during the washing and ironing process by as-prepared solutions to have antibacterial and antifungal properties against toEscherichia coli,Staphylococcus aureus,andCandida albicans. Moreover, we have reported the effect of type of the fabric used and number of washing/impregnation cycles (in a laboratory scale) on the bactericidal and fungicidal activity of obtained textiles. The results indicated that all tested samples after 5, 10, 15, and 20 washing/impregnated cycles exhibited an antimicrobial activity. The antifungal tests showed that only textile impregnated with solutions containing Ag+/Cu2+and Ag NPs/Cu2+exhibited a strong inhibition of fungi growth of the after 5 (99.99%) and 15 (100%) washing/impregnation cycles, respectively.
