Abstract

• Green, sustainable bionanocomposites have the potential to be useful in diagnostic and biomedical applications. In the present study, a series of copper oxide nanoparticles-based carboxymethyl cellulose (CuCMC) bionanocomposites with different weight ratios of carboxymethyl cellulose (CMC) derived from asparagus stalk end to copper oxide nanoparticles (CuO NPs) were prepared. The prepared bionanocomposite of copper oxide nanoparticles based carboxymethyl cellulose (CuCMC) material was characterized by using XRD, FT IR, UV-Visible, SEM and TG-DTA techniques. SEM, and XRD studies indicated the in situ generation of CuO NP in the carboxymethyl cellulose matrix. FT IR analysis confirmed the presence of both CuO NPs and CMC. TG-DTA results indicated that the CMC content of CuCMC was between 61.9 and 73.6 % by weight. Finally, the synthesized CuO, CMC, and CuCMC were tested for their antimicrobial activity. The results obtained from those different studies revealed that carboxymethyl cellulose and copper oxide bionanocompsite can be used effectively for biomedical applications
