Zinc-Metal Organic Frameworks: A Coreactant-free Electrochemiluminescence Luminophore for Ratiometric Detection of miRNA-133a

Xiaoyan Wang et al.

Summary: A novel ratiometric electro-chemiluminescence biosensor utilizing zinc-metal organic frameworks (Zn-MOFs) as a single luminophore has been developed for ultrasensitive detection of miRNA-133a. The biosensor, which does not require an exogenous coreactant, demonstrated excellent accuracy and stability. This study provides a new perspective on fabricating a ratiometric ECL biosensor platform using Zn-MOFs as a single emitter.
