Title: | A metal-catalyst free flexible and free-standing chitosan/vacuum-stripped graphene/polypyrrole three dimensional electrode interface for high performance dopamine sensing | Authors: | Liu, Jing He, Ziming Xue, Jingwen Tan, Timothy Thatt Yang |
Keywords: | DRNTU::Science::Chemistry | Issue Date: | 2014 | Source: | Liu, J., He, Z., Xue, J., & Tan, T. T. Y. (2014). A metal-catalyst free, flexible and free-standing chitosan/vacuum-stripped graphene/polypyrrole three dimensional electrode interface for high performance dopamine sensing. Journal of Materials Chemistry B, 2(17), 2478-2482. | Series/Report no.: | Journal of materials chemistry B | Abstract: | A three dimensional chitosan/vacuum-stripped graphene/polypyrrole interface with a hierarchical porous structure was fabricated as a free-standing and flexible electrochemical sensing electrode for dopamine detection, which exhibits unprecedented good selectivity, high sensitivity (632.1 μA mM−1 cm−2), wide linear response range (0.1–200 μM), low detection limit (19.4 nM, S/N = 3) and good sensing performance in human serum samples, outperforming the previously reported 2D and 3D graphene and/or the PPy modified electrode, and exhibiting comparable performance with the Au modified electrode. | URI: | https://hdl.handle.net/10356/104156 http://hdl.handle.net/10220/19440 |
