Silver nanoparticles (AgNP) have been used as an alternative to microbial resistance. Nevertheless, AgNP high cost and moderate toxicity humans limit their use. Copper (CuNP) emerge alternative, but fast oxidation hampers large-scale In this scenario, work propose the synthesis optimization of Ag, Cu, bimetallic Ag/Cu in a chitosan aqueous solution using factorial design statistics. UV-Vis spectroscopy, zetasizer, transmission electron microscopy (TEM) measurements demonstrated that...
A biobased material, polythymol (PTF), was prepared using thymol, a monoterpene obtained from the essential oil of Thymus vulgaris (Lamiaceae), as starting material with aim enhancing antimicrobial properties this natural product. Initially, different processes were performed in order to optimize reaction conditions obtain macromolecule high purity and yield. PTF characterized techniques, such NMR, infrared, UV-Vis, thermogravimetric analyses. The activity both thymol evaluated against...
The use of copper as an antimicrobial agent has a long history and gained renewed interest in the context COVID-19 pandemic. In this study, authors investigated properties alloy composed with small percentage silver (Cu-0.03% wt.Ag). was tested against various pathogens, including Escherichia coli, Staphylococcus aureus, Candida albicans, Pseudomonas aeruginosa, H1N1 virus, using contact exposure tests. Results showed that capable inactivating these pathogens two hours or less, indicating...
The relentless rise of Multidrug-Resistant (MDR) bacteria significantly challenges global health, undermining the effectiveness traditional antibiotics and demanding prompt development new antimicrobial strategies. This study investigates properties Gamma-Aminobutyric Acid (GABA) silver nanoparticles (GABAAgNPs). GABAAgNPs were synthesized via photoreduction subsequently characterized using UV-Vis spectroscopy, Transmission Electron Microscopy (TEM), Zeta potential analysis. Their was...
Silver nanoparticles (AgNPs) have been extensively explored as an alternative for microbial resistance. However, its high cost and moderate toxicity to humans limit use. As alternative, copper (CuNPs) may be but their fast oxidation hamper large-scale uses. Therefore, we propose here the synthesis optimization of Ag, Cu, Ag/CuNPs in chitosan aqueous solution using factorial design statistics. The optimized synthetic procedure allowed formation stable monodisperse demonstrated by UV-Vis...
