A flexible electrochemical sensor based on Fe-doped polydopamine derived carbon for simultaneous detection of dopamine and uric acid

A free-standing electrode based on carbon cloth-supported Fe-doped polydopamine-derived carbon (Fe/PDA-C/CC) was developed for the simultaneous detection of dopamine (DA) and uric acid (UA). First, dopamine was self-polymerized on the surface of the carbon cloth to obtain polydopamine coatings. Subsequently, Fe
