Sliver nanoparticles (AgNPs) have attracted tremendous interest as an alternative to commercially available antibiotics due their low microbial resistance and broad-spectrum antimicrobial activity. However, AgNPs are highly reactive unstable susceptible fast oxidation. Synthesizing stable efficient using green chemistry principles remains a major challenge. To address this issue, we establish facile route form AgNP-doped zein nanoparticle core–satellite superstructures with ultralow minimum bactericidal concentration (MBC). In brief, polyphenol surface-functionalization of was performed, the epigallocatechin gallate (EGCG) layer on served reducing-cum-stabilizing agent. We used EGCG-decorated (ZE) template direct nucleation growth develop metallized hybrid (ZE-Ag). The monodispersed (∼150 nm) decorated ∼4.9 nm were synthesized successfully. spatial restriction EGCG by confined only surface particles, which prevented formation entangled clusters polyphenols concomitantly inhibited coalescence oxidation AgNPs. Thus, strategy improved effective specific area AgNPs, result, ZE-Ag efficiently killed indicator bacteria, Escherichia coli (E. coli) Methicillin-resistant Staphylococcus aureus(MRSA) after 20 min incubation, MBCs 2 4 μg/mL, respectively. This situation indicated that as-prepared possessed potent short-term sterilization capability. Moreover, simulated wound infection model also confirmed promising application composite. work provides new insights into synthesis emerging in food preservation, packaging, biomedicine, catalysis.

Abstract Background Novel platforms using nanotechnology-based medicines have exponentially increased in our daily lives. The unique characteristics of metal oxide and noble metals nanoparticles make them suitable for different fields including antimicrobial agents, cosmetics, textiles, wound dressings, anticancer drug carriers. Methods This study focuses on the biosynthesis small-sized SNPs exo-metabolites Fusarium oxysporum via bioprocess optimization Plackett-Burman (PBD) central composite designs (CCD) while evaluating their multifaceted bioactivities. Results successful biofabrication smaller-sized with an average particle size ~ 5 nm was achieved upon optimization. developed exhibited significant antibacterial activity against multidrug-resistant bacterial pathogens a concentration- time-dependent manner. minimum inhibitory concentrations (MICs) were 0.078 µg/ml ( Escherichia coli ), 0.156 Pseudomonas aeruginosa 1.25 Enterococcus faecalis bactericidal (MBCs) correspondingly µg/ml, 0.312 µg/l, µg/ml. SNPs-treated cells displayed bacteriostatic effects as revealed by time-kill assay ultrastructure changes observed SEM TEM analyses. results marked potent antioxidant DPPH, O 2 •− , H OH-radicals IC 50 values 74.3, 96.7, 116.6, 167.9 respectively. Significantly, biosynthesized cytotoxic MCF-7, A549, HepG-2 cell lines 89.4, 121.4, 138.9 promising photocatalytic efficiency at times compared dark conditions. highest decolorization percentage crystal violet dye 98.60% after 240 min 100 µg concentration. Conclusions green synthesis F. exometabolites is eco-friendly, inexpensive, production small-size, greatly stabilized nanoparticles. corroborated that can be highly enough to applied control systems, ameliorating free radical-related disorders, photocatalyst wastewater treatment.

Abstract In this study, Ag@Cu alloy nanoparticles and silver nanowires (AgNWs) were synthesized by a green method using the Pterospermum heterophyllum extract. To study influence of precursor ratio on synthesis Ag@Cu, molar Ag Cu was changed to 10:7, 10:6, 10:5, 10:4. concentration formation AgNWs, AgNO 3 varied with values such as 3, 4, 5, 6, 7, 8 mM. The results showed that spherical formed uniformly when Ag:Cu high. branched structures appeared 10:6 10:7. AgNWs strongly depended concentration, similar polyol method. 5 mM most suitable for AgNWs. have been studied surface-enhanced Raman scattering effects MB dye. both types particles could enhance enhancement factors up 10 9 . This proved products equivalent applications chemical methods.
