Abstract
Zelena sinteza je metoda koja za sintezu nano estica koristi netoksi ne i biorazgradive kemikalije. U ovome istraživanju prvi put je prikazana sinteza nano estica srebra upotrebom vodenog ekstrakta gljive Ophiostoma novo-ulmi i vodene otopine AgNO3. Ophiostoma novoulmi je fitopatogena gljiva mjebinarka koji uzrokuje holandsku bolest brijesta (DED). Biosintetizirane nano estice srebra karakterizirane su UV-Vis, FT-IR i PXRD tehnikama. Rezultati karakterizacije sintetiziranih nano estica ukazuju na uspjebnu sintezu koribtenjem ekstrakta O. novo-ulmi kao reduciraju eg i stabiliziraju eg sredstva, s UV-Vis maksimumom na ≈ 413 nm. FT-IR analizom su identificirani glavni fitokemijski spojevi koji bi mogli biti odgovorni za bio-redukcijski potencijal. Prema rezultatima PXRD, promjer kristalita AgNP-a izra unat pomo u Scherrer-ove jednadžbe iznosi 30 nm, sa plobno centriranom kubi nom (fcc) strukturom.
Abstract (english)
Green synthesis is a method that uses non-toxic, biodegradable chemicals for the synthesis of nanoparticles. In the present study, we report for the first time a green approach to the synthesis of silver nanoparticles (AgNPs) using an aqueous extract of the fungus Ophiostoma novo-ulmi and an aqueous solution of AgNO3. Ophiostoma novo-ulmi is a phytopathogenic ascomycete that causes Dutch elm disease (DED), a devastating vascular wilt disease of elms. The biosynthesised nanoparticles were characterised by UV-Vis, FTIR and PXRD. The results of the characterisation of the synthesised nanoparticles indicate the successful synthesis using O. novo-ulmi extract as a reducing and capping agent, with a UV-Vis absorption peak at≈ 413 nm. FTIR identified major phytochemical compounds that could be responsible for the bio-reducing potential. According to the PXRD results, the AgNP crystallite diameter calculated using the Scherrer equation is 30 nm, with a face centred cubic (fcc) structure.
