Functional polymer for polymer electrolyte and biosensor applications

F
or 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 methacrylate-
acrylate 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).
