英文摘要： As the thinnest two-dimensional crystal, graphene, with unique electrical properties and high specific surface area, has received much research interest in recent years. Two-dimensional layered transition metal dichalcogenides (LTMDs), whose structure is similar to that of graphene (G), has strong adsorption capacity, a great number of catalytic active sites and high catalytic efficiency. In this research project, we intend to fabricate a novel composite material with LTMDs and G based on their wonderful structure and unique performance. Based on the matching of crystal structure and morphology and complementarity of electrical properties, it is supposed that the nanocomposite materials, for the most part, could display the synergistic effect between LTMDs and G. The present program will focus on the synthesis, structural characterization and study for the excellent optoelectronic properties of LTMDs/G, and to construct the interfacial biorecognition platform, and researching on the biological sensing analysis. We will develop novel techniques with excellent performances based on the interfacial biomolecular recognition, electrochemical and bio-catalytic amplification and signal transformation. The current project is an important subject in the world which is still in its infancy, and would be promising to address the significant issues in early diagnosis of major diseases and new sensing technology.
