Cellulose from Musa balbisiana was purified. A part of it was dispersed in distilled water using ultrasonication. The silver nanoparticles (SNP) were synthesized in the colloidal cellulose solution and stability of the nanoparticles was tested using UV–Vis spectrophotometer. Further characterization of the composite was done using spectral analysis by Fourier Transform Infrared Spectroscopy (FTIR) to reveal any bond formation between silver nanoparticles with M. balbisiana cellulose. Here we found that cellulose/silver nanoparticle colloid is stable for 29 days and there is no chemical interaction of cellulose with silver nanoparticles.
