Popis:	Molecular imprinted polymer (MIP) is a technique to produce a template-shape cavities in polymer matrix with memory of the template/target molecule for chemical sensor front-end development. In this study, it has been shown that the incorporation of graphene sheet congo-red (GSCR) has enhanced the performance of Organic Thin Film Transistor (OTFT) amino acid (serine) chemical sensor. The sensor has a lower detection limit of 70 ppm serine concentration with a good repeatability and reproducibility. The GSCR-MIP sensor has a good potential for other application such as detecting amino acid biomarkers for early detection of cancer disease in blood.
