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 H 2 O 2 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.
