An electrochemical sensor for sensitive detection of dopamine based on a COF/Pt/MWCNT–COOH nanocomposite

Herein, an electrochemical sensor was developed for sensitive detection of dopamine (DA) based on a novel COF-based nanocomposite named COF/Pt/MWCNT-COOH, which possesses large specific surface area, excellent electrical conductivity, and high catalytic activity, thus broadening the application of COFs in the electrochemical sensing area.
