Responsive Ag@NiCo(2)O(4) Nanowires Anchored on N-Doped Carbon Cloth as Array Electrodes for Nonenzymatic Glucose Sensing

The development of responsive materials in a predictable manner is high on the list of the material industry’s trends. In this work, responsive Ag@NiCo(2)O(4) nanowires were, firstly, anchored on N-doped carbon cloth (NC) and, then, employed as array electrodes for a nonenzymatic glucose-sensing application. The results showed that the highly conductive NiCo(2)O(4) nanowires supported Ag nanoparticles and exhibited high conductivity and electrocatalytic properties. The fully exposed crystalline planes of Ag nanoparticles provided more active surface sites. As a result, the assembled Ag@NiCo(2)O(4)-NC electrodes for the glucose-sensing evaluation delivered a selectivity of 2803 μA mM(−1) cm(−2) and a detection limit of 1.065 μM, which outperformed the literature-reported Ag- and NiCo(2)O(4)-based glucose-sensing catalysts.
