Abstract: Molecular imprinted is a technique to produce template-shape cavities in polymer matrix with memory of the template/target molecule for chemical sensor front-end. In this study, it has been shown that the incorporation of graphene sheets/Congo red (GSCR) has enhanced the performance of molecular imprinted polymer (MIP) serine sensor. The polymer is formed via photo-polymerization from methyl methacrylate acid (functional monomer), serine (template) and ethylene glycol dimethacrylate (cross-linker) together with GSCR. By introducing GSCR-MIP, GSCR-MIP OTFT chemical sensor demonstrates a good response when serine is introduced. The performance of GSCR-MIP OTFT serine sensor can be improved through the addition of GSCR, thus GSCR-MIP has high potentials for application in sensor fabrication.
