Abstract
A facile strategy for in-situ growing triethanolamine (TEOA)-functionalized metal-organic framework (TEOA@MOF) on the 2D graphene oxide (GO) or g-C3N4 nanosheets via the self-assembly technique was introduced. In this method, Zn2+ was firstly attached on the carbon nanosheets by electrostatic interaction, then trimesic acid (H3btc) acted as the complex agent and TEOA as a base for the deprotonation of H3btc and a template, which leads to in situ growing the MOF on the carbon nanosheets obtaining a sandwich-like structure. Different types of surface analysis techniques were employed to characterize the GO-TEOA@MOFs and g-C3N4-TEOA@MOFs nanomaterials fabricated. The GO-TEOA@MOFs or g-C3N4-TEOA@MOFs nanomaterials modified electrode brings out obviously enhanced ECL behaviors due to numerous TEOA in the framework structures. Specifically, both TEOA and GO can serve as the co-reactants for ECL system of Ru(bpy)32+ and have the synergic effect of enhancing signal. Based on the GO-TEOA@MOFs modified electrodes, we developed a sensitive and rapid label-free ECL immunoassay strategy for human copeptin, and the linear range was 5 pg mL-1 ‒500 ng mL-1 as well as the limit of detection was 360 fg mL-1. This work exhibits excellent specificity and good stability of prepared immunosensor in the practical sample determination, demonstrating it can serve as a very promising method for the clinical diagnostics of acute myocardial infarction (AMI) disease.
