Nonenzymatic electrochemiluminescence glucose sensor based on quenching effect on luminol using attapulgite–TiO2

A new nonenzymatic glucose ECL sensor based on attapulgite (Att) integrated with semiconductor material TiO2 was developed. The prepared material was characterized by transmission electron microscopy (TEM), X-ray diffractometer (XRD), electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). Based on ECL experimental results, Att–TiO2 composites were found to be able to improve the ECL properties of luminol. When glucose is added...
