Abstract
We report a facile strategy for the synthesis of gold nanobone/carbon nanotube (CNT@GNB) nanoassemblies, which were prepared through hybridization of CNTs and GNBs mediated by a thiolated pyrene derivative. The SEM images confirmed the successful construction of the CNT@GNB nanoassemblies. Screen printed electrodes modified with the CNT@GNB nanoassemblies exhibited decent electrocatalytic activity, large surface-tovolume ratios, high electrochemical reversibility, and efficient electron transport properties, thereby enabling stable and sensitive nonenzymatic detection of H2O2 and glucose, with detection limits of 0.8 mM and 0.07 mM, respectively. Moreover, no interference was observed at a potential of +0.38 V for the interfering species, such as ascorbic acid and urea, indicating high selectivity toward the glucose detection.
