Summary
This summary is machine-generated.

This study introduces a novel electrochemiluminescence (ECL) biosensor using pyrene-derived covalent organic frameworks (pyr-COFs) and Pd2+ ions for enhanced sensitivity. The renewable biosensor accurately stages glioma by correlating dopamine (DA) and miRNA-21 levels using machine learning.
