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.
