At present, it is an important research area in life analytical chemistry that preparation of biomolecule-functionalized carbon nanomaterial composite modified electrodes which possess biocompatibility and special recognition function. This program will study on the synthesis of biomolecules-functionalized carbon nanomaterial and the preparation as well as application of its composite modified electrode. From the beginning, the carbon nanomaterials are biomolecules-functionalized, and then formed carbon nanomaterial composites combined ionic liquid or magnetic material which possesses biocompatibility. Furthermore, they are assembled on the surface of the electrodes, and construct bio-interface which has biologic special recognition and biologic catalytic function for the substrates. We hope to develop new methods and techniques in biosensors with high sensitivity and high selectivity. Meanwhile, we will discuss the interaction of biomolecules, nanomaterials and ionic liquids, and investigate mechanism of electrocatalysis of modified electrodes, providing theory and experimental base for setting up new methods as well as obtaining information in biological system.
