New synthetic protocols are extensively being explored for the synthesis of mono disperse metal NCs, because of their promising applications in the field of optoelectronics, bio-imaging, biological sensing, and catalysis. Due to the increasing popularity of green methods, different works had been done to synthesize metal oxide NPs using different sources. In this present study natural gum contains a water soluble polysaccharide as L-arabinose and D-galactose was used to evaluate to synthesis metal oxide nanoparticle.
