Novel Electrochemical Biosensors Based On Ionic Liquid And Nanocomposites

In this paper, several sensitive electrochemical biosensors were successfully realized on ionic liquid and nanocomposites modified electrodes. The resulted electrochemical biosensors were prepared and used to detect biologic molecule.The paper is made up of five parts. Firstly, a summary referring to the development of the ionic liquid electrochemical biosensor and the application in biosensing of nanocomposites are reviewed. The second part and the third part are reported on two novel nonenzymatic amperometric glucose biosensors based on ionic liquid and Nickel nanoparticle. The loading of the ionic liquid and Nickel nanoparticle are greatly enhanced and the sensitivity for the glucose detection is markedly improved. In the fourth part and the fifth part, hexacyanoferrate nanoparticles membranes on the carbon ionic liquid electrode are constructed for the electrochemical sensing of the guanine and adenine detection. The conditions for the modified electrode are optimized and the biosensors also have good selectivity, stability and reproducibility.
