All-Optical Electrochemiluminescence

Journal of the American Chemical Society, 2023
Electrochemiluminescence (ECL) is widely employed for medical diagnosis and imaging. Despite its remarkable analytical performances, the technique remains intrinsically limited by the essential need for an external power supply and electrical wires for electrode connections.

Luciferase‐free Luciferin Electrochemiluminescence

Angewandte Chemie International Edition, 2022
AbstractLuciferin is one of Nature's most widespread luminophores, and enzymes that catalyze luciferin luminescence are the basis of successful commercial “glow” assays for gene expression and metabolic ATP formation. Herein we report an electrochemical method to promote firefly's luciferin luminescence in the absence of its natural biocatalyst ...
