Abstract

For this study, a paper impregnated with silver nanoparticles (AgNPs) was prepared. To prepare the substrates, aqueous suspensions of pulp fines, a side product from the paper production, were mixed with AgNP suspensions. The nanoparticle (NP) synthesis was then carried out via laser ablation of pure Ag in water. After the sheet formation process, the leaching of the AgNPs was determined to be low while the sheets exhibited antimicrobial activity toward Escherichia coli (E. coli).

Keywords: antimicrobial activity; fiber fines; laser ablation in liquids; laser synthesis of colloidal nanoparticles solution; nanoparticle-impregnated paper; sheet forming; silver nanoparticles; vacuum filtration.
