Poly(brilliant cresyl blue) electrogenerated on single-walled carbon nanotubes modified electrode and its application in mediated biosensing system.
Single-walled carbon nanotubes (SWCNTs) functionalized with carboxylic acid groups were cast to glassy carbon electrode (GCE) to construct a three-dimensional nano-micro structured scaffold. Brilliant cresyl blue (BCB) was electropolymd. on the above-mentioned SWCNTs/GCE using continuous cycling between -0.7 and 0.9 V vs. SCE. PolyBCB yielded on SWCNTs/GCE exhibited the enhanced electrochem. redox behavior compared with that electrogenerated on bare GCE. The apparent surface coverage of PolyBCB obtained by SWCNTs/GCE was at least 10 times higher than that obtained by bare GCE, namely 4.8 × 10-9 and 3.6 × 10-10 mol cm-2. The cyclic voltammograms recorded by PolyBCB/SWCNTs/GCE exhibited well-defined two peaks located at -0.25 V and -0.06 V, resp., with a surface-controlled mechanism. In addn., morphologies of PolyBCB electrogenerated on GCE and SWCNTS/GCE were characterized by AFM. Finally, this proposed PolyBCB/SWCNTs/GCE was used in the construction of the second-generation biosensors to H2O2 and glucose, with the enhanced anal. performance. [on SciFinder(R)]
