Abstract:

For the past decade, much attention was focused on polysaccharide natural resources and methacrylate polymer for various purposes. Our group has been interested into functionalized polymer for exploring novel functions. Throughout the works, several efforts were done to prepare new function of chitosan by chemical modifications for biopolymer electrolyte. We focus on the synthesis of the chitosan derivative, namely, O-nitrochitosan which was synthesized at various compositions of sodium hydroxide. Its potential as biopolymer electrolytes was studied. We also have been working on functionalized polymer for the fabrication of Sunset Yellow and Tartrazine biosensors. The polymer used was in the form of thin film and microspheres for Sunset Yellow and Tartrazine biosensors respectively. The biosensor for Sunset Yellow was developed by coating a peelable poly (acrylamide-co-ethyl methacrylate) film with immobilized laccase prepared by photopolymerization on a glassy carbon electrode (GCE). Tartrazine biosensor was designed with a functionalized methacrylateacrylate microsphere immobilized with laccase and gold nanoparticles composite coated on a carbon paste screen printed electrode. Both biosensors were analyzed by cyclic voltammetry (CV) and differential pulse voltammetry (DPV).
