Abstract
In the present study, nanocellulose, extracted from fully bleached kraft pulp by sulfuric acid hydrolysis, was firstly oxidized using periodate to obtain dialdehyde nanocellulose (DANC). Then, DANC was used as both reducing and stabilizing agent to prepare Ag-NPs. The synthesized Ag-NPs were characterized by using UV-Vis spectroscopy, X-ray diffraction (XRD), and atomic absorption spectroscopy (AAS). Furthermore, the antimicrobial activity was investigated. The addition of DANC to silver nitrate solution resulted in color change from white to dark brown at varied pH. The formation of Ag-NPs was evidenced by measuring the surface plasmon resonance peak at around 400 nm using UV-vis spectroscopy. XRD data showed diffraction peaks at 2 38.33§, 44.55§, 64.27§, 77.66§, which can be indexed to (111), (200), (220), (311), and (222) planes of pure silver, indicating he biosynthesis of silver nanoparticles The synthesized Ag-NPs showed high antimicrobial and bactericidal activity against Gram-positive and Gram-negative bacteria.
