title: One-Step Electrodeposition of NiCo2 S4 Nanosheets on Patterned Platinum Electrodes for Non-Enzymatic Glucose Sensing.
abstract: The preparation of NiCo2 S4 (NCS) nanosheets on photolithographically patterned platinum electrodes by electrodeposition was explored. The as-prepared nanosheets were systematically characterized by field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy techniques. The NCS-modified Pt electrode was used as a non-enzymatic glucose sensor. The sensor response exhibited two linear regions in glucose concentration, with a limit of detection of 1.2 μm. The sensors showed that the as-prepared NCS nanosheets have excellent electrocatalytic activity towards glucose with long stability, good reproducibility, and excellent anti-interference properties, and thus, this material holds promise for the development of a practical glucose sensor.
