Green-Synthesized Nanoparticles to Combat Multidrug-Resistant Bacteria

Published: Jan. 1, 2024

Antibiotic resistance has rapidly climbed in recent years, threatening millions of lives worldwide and presenting a serious threat to community health. Since spread widely many different species bacteria share genes, multidrug-resistant (MDR) microorganisms have come light. This led international efforts develop new improved antibacterial materials treat with multidrug resistance. Global interest is currently growing the utilization innovative biomaterials made nanoparticles (NPs) completely achieve this accomplishment. For treatment drug-resistant infections, NPs may prove be vitally important therapeutic option. The metals metal oxide seem most potential all classes grabbed curiosity numerous researchers. Due their special physicochemical characteristics, such as gold, silver, iron oxide, copper, zinc titanium dioxide. Have demonstrated effects at very low concentrations. Synthesis by physical chemical procedures can result environmental contamination, health risks humans, technological issues, high costs, ineffectiveness. To address these emerging popularity are biological methods that use safe, non-toxic substances during synthesis process. process known "green synthesis" produces using sources, which act reducing capping agents. There fight bacteria, including interference bacterial biofilms, disruption cell membranes, generation reactive oxygen (ROS). These mechanisms lessen possibility developing while preventing growth. produced green offer potentially effective method for battling multiple MDRs addition weapons antimicrobial agents due environmentally friendly production practices, strong toxicity.

Green Synthesis of Au‐Ag@TiO₂ Nanocomposite for Photocatalytic Oxidation of Substituted Benzyl Alcohols

ChemistrySelect, Journal Year: 2024, Volume and Issue: 9(27)

Published: July 16, 2024

Abstract The scaling‐up of methodologies in the oxidation alcohols to carbonyl compounds faced widespread hindrance industries due large‐scale use toxic and expensive metal oxidants. Novel, cost‐effective eco‐friendly approaches need be developed address these problems. Bimetallic nanoparticles (BMNPs) show synergistic effects at atomic level, which makes them excellent catalysts for organic transformations. Transition nanocomposite with unique physicochemical properties high surface area offers a promising alternative traditional catalysts. Herein, an environment‐friendly methodology was adopted synthesis Au−Ag BMNPs using phenolic‐rich Ocimum basilicum (L.) leaf extract, then incorporated into TiO 2 matrix plasmonic Au−Ag@TiO nanocomposite. formation confirmed through analytical characterizations, such as UV–Vis. DRS, FT‐IR, PL, SEM, TEM XRD. exhibited catalytic activity selective primary secondary aqueous media H O oxidant under visible light irradiation room temperature. also demonstrated good reusability 84 % fifth cycle, established its candidature wide‐scale applications. This work holds significant relevance dealing pharmaceuticals personal care products, thus, sustainable solution

Synergistic Antifungal Efficiency of Eco-Friendly Synthesized Zinc Oxide Nanoparticles in Combination with Fluconazole against Drug-Resistant Candidal Strains

Polish Journal of Environmental Studies, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 5, 2024

The resistance of fungal pathogens to traditional antifungal medications presents a significant public health concern, particularly for immunocompromised patients, leading elevated rates illness and death.This study aimed explore the properties zinc oxide nanoparticles (ZnO NPs) produced using natural approach involving aqueous seed extract Trigonella foenumgracium (Fenugreek).Additionally, assessed combined effectiveness these biologically synthesized ZnO NPs with fluconazole against pathogens.The were observed have hexagonal shape an average diameter 27 nm surface charge -18.3 mV.Notably, exhibited most potent activity Candida tropicalis, relative inhibition zone 18.67±0.56mm.The minimum inhibitory concentration C. tropicalis was determined be 100 µg/mL, while fungicidal found 200 µg/mL.The greatest synergistic effect between glabrata, followed by parapsilosis.In summary, underscores potential combining formulate effective treatment drug-resistant pathogens, thereby enhancing therapeutic efficacy conventional drugs.
