Investigation of Size Effects on the Synthesis of Graphene Nanoribbons for Electrochemical Biosensor Applications

The size effects on the synthesis of graphene nanoribbons for electrochemical biosensor applications will be studied in this project. Experimentally we plan to use microwave-assisted synthesis to unzip multi-walled carbon nanotubes with various lengths and diameters, single- as well as double-walled carbon nanoutbes. All kinds of graphene nanoribbons will be characterized by different analysis methods so as to be integrated in the electrochemical biosensors to detect the analytes (especially dopamine). As for international collaboration, we will continue to work with the Canadian scientists (University of Saskatchewan) and use scanning transmission X-ray microscopy (STXM). We will investigate the electronic structures of graphene nanoribbons and their relationship with the detection current. Regarding to the domestic collaboration, we will work with the associate professor at NCU to access the small-angle X-ray scattering (SAXS) instrument. We will study how the microwave power in processing and the storage time of inks affect the cross-sectional morphology of graphene nanoribbons as well as their detection currents. Besides our experimental and theoretical experiences in carbon nanotube and graphene in early publications, (Chem. Mater. 2005, 17, 3749. Citation ＞ 110, IF = 7.286, N/M = 5.6%; J. Am. Chem. Soc. 2006, 128, 8368. IF = 9.907, N/M = 7.2%; J. Mater. Chem. 2011, 21, 14622. IF = 5.968, N/M = 7.4%; Biosens. Bioelectron. 2011, 26, 3450. (The average citation number per year is 21 times.) IF = 5.602, N/M = 3.7%; Carbon 2012, 50, 4192. IF = 5.378, N/M = 9.1%) we already have some results which can prove this proposal is doable as well as valuable. (ACS Nano 2011, 5 (10), 7788. IF = 11.421, N/M = 3.9%) It is believed that we must be able to contribute to the development of nanocarbon materials with significant research achievement and publications.
