title: Ternary NiCoP nanosheet array on a Ti mesh: a high-performance electrochemical sensor for glucose detection.
abstract: Electrode design is of significant importance in the construction of enhanced electrochemical sensing platforms, and nanoarrays are an attractive architecture in molecule detection with large specific surface area and easy access for target molecules. In this communication, we report on the development of a ternary NiCoP nanosheet array on a Ti mesh (NiCoP/Ti) as a non-noble metal efficient catalyst electrode for electro-oxidation of glucose in alkaline electrolytes. As an electrochemical sensor for glucose detection, NiCoP/Ti shows a fast response time of less than 3 s, a low detection limit of 0.13 μM (S/N = 3), and a high sensitivity of 14 586 μA mM-1cm-2. This sensor is also stable with high selectivity, specificity and reproducibility, and its application for real sample analysis is also demonstrated successfully.
