A novel metal-organic framework loaded with abundant N-(aminobutyl)-N-(ethylisoluminol) as a high-efficiency electrochemiluminescence indicator for sensitive detection of mucin1 on cancer cells

Herein, a high-efficiency electrochemiluminescence (ECL) indicator of an abundant N-(aminobutyl)-N-(ethylisoluminol)functionalized metal-organic framework (ABEI@Fe-MIL-101) was synthesized to construct a biosensor for the ultrasensitive assay of mucin1 on MCF-7 cancer cells with a coreactant H2O2-free strategy.
