Abstract:
In order to overcome the poor solubilities of iridium-based ECL luminophores and explore self-enhanced ECL luminophores, polyethyleneimine (PEI) covalently linked with iridium complex via amide bonds (abbreviated as Ir-PEI) as a new novel intramolecular self-enhanced water-soluble ECL reagent has been unprecedently designed and successfully synthesized in this work. The chemical structure data, FT-IR spectra, photophysical, electrochemical and electrochemiluminescence of this new ECL reagent have been well characterized. In addition, in order to investigate its properties in the real applications, a corresponding new sensitive and specific ECL-based aptasensor to monitor tetracycline (TET) residues in honey and lake water has been further constructed based on this novel self-enhanced reagent of Ir-PEI in this work. This as-prepared intramolecular self-enhanced water-soluble of Ir-PEI illustrated in this work would pave a new avenue to promote the analytical applications of iridium-based ECL luminophores in the future.

There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or...
