Preparation of Silver-Incorporated Rhynchospora corymbosa (L.) Cellulose via in-situ Green Reduction and Its Antibacterial Study

Silver incorporated R. corymbosa (L.) cellulose was obtained through the direct attachment (insertion) of silver ions to natural cellulose, followed by the green reduction of ions to metallic silver, using aqueous extract of fresh R. corymbosa (L.). In addition, Fourier transform infra-red (FTIR) analysis of the isolated cellulose showed some peaks at 3330 cm −1 , 2890 cm −1 , 1320 cm −1 , 1030 cm −1 , 895 cm −1 corresponding to OH stretching, methylene (-CH 2 -) stretching, OH bonding, C-O bonding, and 1,4 β-glycoside, respectively. The silver incorporated R. corymbosa (L.) cellulose was prepared by impregnating silver ions obtained from silver nitrate solution, followed by ion reduction to the metallic silver in-situ . Furthermore, another interesting outcome of this study is seen in the products’ ability to show inhibition zones in the growth medium of Escherichia coli .
