Aqueous Cymbopogon citratus Extract Mediated Silver Nanoparticles: Part I. Influence of Synthesis Parameters, Characterization, and Biomedical Studies

Nanomaterials, Год журнала: 2025, Номер 15(5), С. 328 - 328

Опубликована: Фев. 20, 2025

This study explores the green synthesis of silver nanoparticles (AgNPs) using Cymbopogon citratus (lemongrass) extract as a reducing agent. Synthesis was confirmed by color change (light yellow to dark brown) under optimal conditions: 1.50 mM nitrate, 3.5% v/v extract, at 100 °C, with pH 9, and for 60 min. The AgNPs exhibited spherical morphology, hydrodynamic diameter 135.41 ± 49.30 nm, zeta potential -29.9 1.4 mV, crystalline structure, minimal aggregation. showed significant antibacterial activity, particularly >20 µg/well, zones inhibition varying bacterial strain. In vitro studies demonstrated anti-inflammatory, antidiabetic (α-glucosidase α-amylase inhibition), antioxidant activities, outperforming plant nearing standard efficacy higher concentrations. Cyto-toxicity indicated that were less toxic than doxorubicin but concentration-dependent effects on cancerous non-cancerous cells. Eco-toxicity assays revealed acutely controls posed risks prolonged exposure. work highlights eco-friendly their in biomedical applications, demonstrating activities.

Silver nanoparticles (AgNPs) are widely recognized for their unique optical, electronic, and antibacterial properties, enabling use in biosensing, photonics, electronics, drug delivery, antimicrobial treatments. Green chemistry-based biological synthesis methods offer an eco-friendly alternative to traditional chemical techniques. Among metallic (NPs) metal oxides, those derived from plant extracts exhibit notable medicinal properties. Due exceptional stability low reactivity, AgNPs particularly well-suited various applications. can be synthesized through chemical, physical, or methods, each with distinct benefits challenges. Chemical physical approaches often involve complex purification, reactive reagents, high energy demands, while though slower, provide sustainable solutions. The chosen method strongly influences the stability, size, purity of resulting NPs. This review emphasizes importance selecting appropriate optimize characteristics functionality silver It consolidates research spanning past two decades, including most recent findings 2024. A comprehensive electronic search databases such as PubMed, Scopus, ScienceDirect, Cochrane, Google Scholar was conducted up-to-date overview advances applications nanoparticles.

Glycine-modified chitosan-embedded silver nanoparticles: a green approach to Pb2+ adsorption and bioactivity enhancement

Chemical Papers, Год журнала: 2024, Номер unknown

Опубликована: Дек. 10, 2024

Abstract Glycine-modified chitosan anchored silver nanoparticles (SCG) were synthesized using a green method without cross-linking agent. UV–Vis, FTIR, XRD, TEM and SEM techniques confirmed the formation of SCG nanocomposite nanoparticles. The nanoparticles, estimated at 20 nm, are smaller than stabilized Ag (SC) biological significance was assessed through their anti-oxidant antibacterial activities. demonstrated significant activity with an IC50 133 µg ml −1 , surpassing that SC ZoI found to be 30 mm for S. aureus E. coli bacterial strains indicating excellent antimicrobial activity. efficiency in removing Pb 2+ ions tested batch adsorption process. A Central Composite Design (CCD) employed optimize independent variables, ANOVA results indicated CCD model’s reliability p -value < 0.0001. exhibited high ion loading capacity 270.2 mg g from aqueous solution removal 93%. Isotherm kinetic investigations equilibrium data suggest suitability Langmuir pseudo-second-order models. Thermodynamic studies revealed process’s spontaneity exothermic nature. mechanism exchange mean potential energy ( E s ) 9.4 kJ/mol. These findings glycine-modified have promising applications environmental domains.
