Green synthesis of silver nanoparticles using Fomes Fomentarius (L.) extract

Zelena sinteza nanočestica srebra zbog svojih načela pridonosi održivom razvoju bez štetnog utjecaja na okoliš. Nanočestice srebra zbog svojih specifičnih antimikrobnih svojstava nalaze sve veću primjenu u medicinske svrhe. Cilj ovoga rada je sintetizirati nanočestice srebra iz vodenog ekstrakta gljive Fomes fomentarius i otopine AgNO3. Morfologija, stanište, upotreba gljive i zelena sinteza nanočestica srebra opisani su u literaturnom pregledu. Karakterizacija nanočestica izvršena je metodama UV-Vis, FT-IR, PXRD i TEM analize. UV-Vis analizom utvrđen je maksimum apsorbancije pri 410 nm. Rezultati FT-IR analize ukazali su na biomolekule koje su sudjelovale u procesu sinteze nanočestica. Prosječna veličina kristalita iznosila je 24 nm. Nanočestice srebra pokazale su dobru sposobnost razgradnje boje metilenskog plavila. Najbolju antibakterijsku aktivnost uzorak nanočestica srebra pokazao je na sojeve bakterija S. auerusa i E. coli, dok najmanju na soj bakterija P. aeruginosa.Due to its principles, the green synthesis of silver nanoparticles contributes to sustainable development without harmful impact on the environment. Silver nanoparticles are increasingly used for medical purposes due to their specific antimicrobial properties. The aim purpose of this work is to synthesize silver nanoparticles from the aqueous extract of the fungus Fomes fomentarius and AgNO3 solution. The morphology, habitat, use of the fungus and green synthesis of silver nanoparticles are described in the literature review. Nanoparticles were characterized by UV-Vis, FT-IR, PXRD and TEM analysis methods. UV-Vis analysis determined the maximum absorbance at 410 nm. The results of the FT-IR analysis indicated that the biomolecules had participated in the process of nanoparticle synthesis. The average crystallite size was 24 nm. Silver nanoparticles showed a good ability to degrade the color of methylene blue. The sample of silver nanoparticles showed the best antibacterial activity against bacteria S. auerus and E. coli, while the least activity against the strain of bacteria P. aeruginosa
