Abstract:
A binder-free Ru@NiMoS electrode was engineered by in situ growth of two-dimensional NiMoS nanosheets on nickel foam. This process effectively promoted the electrostatic-driven aggregation of Ru(bpy)3 2+, harnessing the synergistic effect to enhance electrochemiluminescence (ECL) performance. The integration (Ru@NiMoS) achieved an impressive ECL efficiency of 70.1%, marking an impressive 36.9-fold enhancement over conventional Ru. Additionally, its ECL intensity was found to be remarkably 172.2 times greater than that of Ru. Within the Ru(bpy)3 2+/TPA system, NiMoS emerged as a pivotal electrochemical catalyst, markedly boosting both the oxygen evolution reaction and the generation of reactive intermediates. Leveraging these distinctive properties, a highly efficient ECL sensor for lidocaine detection was developed. This sensor exhibited a linear response within the concentration range of 1 nM to 1 μM and achieved a remarkably low detection limit of 0.22 nM, underlining its substantial potential for practical application.

Labeling DNA Probes
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...
