ANTIMICROBIAL PROPERTIES OF THE HYBRID COPPER NANOPARTICLES-CARBOXYMETHYL CELLULOSE

摘要

In this study, a simple method to produce a cellulose-based material with antimicrobial properties was developed by introducing copper nanoparticles on carboxymethyl cellulose (CMC) using sodium borohydride as a copper reducing agent. The hybrid material was characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and transmission electron microscopy (TEM). SEM and EDX analysis confirmed the formation of copper nanoparticles within the CMC matrix. TEM indicated a 10- to 20-nm diameter of copper nanoparticles. Antimicrobial properties of the hybrid material were effectively evaluated against the nonpathogenic surrogate of foodborne pathogen Escherichia coil.
