Silver nanoparticles (AgNPs) are excellent antimicrobial agents and promising candidates for preventing or treating bacterial infections caused by antibiotic resistant strains. However, their increasing use in commercial products raises concerns about environmental impact. In addition, traditional physicochemical approaches often involve harmful excessive energy consumption, resulting AgNPs with short-term colloidal stability silver ion leaching. To address these issues, we designed stable hybrid lignin–silver (AgLigNPs) intended to effectively hit envelopes as a main target. The lignin (LigNPs), serving reducing stabilizing agent AgNPs, have median size of 256 nm circularity 0.985. These LigNPs were prepared using the dialysis solvent exchange method, producing spherical particles under alkaline conditions featuring groups oriented toward wrinkled surface, facilitating synthesis attachment. Maximum accumulation on LigNP surface was observed at mass reaction ratio mAg:mLig 0.25, pH 11. AgLigNPs completely inhibited suspension growth reduced biofilm development 50% three tested strains Pseudomonas aeruginosa concentration 80/9.5 (lignin/silver) mg L–1. Compared unattached required two eight times lower concentrations achieve complete inhibition. Additionally, our silver-containing nanosystems effective against bacteria safe HEK-293 HaCaT tissue cultures. Stability experiments revealed that tend aggregate media used cell cultures but remain all media, retained integrity, presence facilitated prevention ions from Overall, data demonstrate suitability further valorization biomedical sector.

Metal nanoparticle synthesis via environmentally friendly methods is gaining interest for their potential advantages over conventional physico-chemical approaches. Herein, we propose a robust green route lignin-modified silver nanoparticles, utilizing the recovery of lignin as renewable raw material and exploring its application in valuable areas. Through systematic approach combining UV-Vis spectroscopy with AAS DLS, identified repeatable scalable reaction conditions an aqueous solution at pH 11 homogeneous nanoparticles high uniformity. The TEM median sizes ranged from 12 to 15 nm circularity between 0.985 0.993. yield exceeded 0.010 mol L−1, comparable traditional methods, minimal loss precursor ranging 0.5 3.9%. Characterization by XRD XPS revealed presence Ag-O bonding involving functional groups on pure face-centered cubic structure metallic silver. Moreover, generated localized thermal effect upon near-infrared laser irradiation (808 nm), potentially allowing targeted applications biomedical field. Our study showcases reducing capping agent synthesis, addressing some shortcomings approaches contributing development suitable nanomaterials.
