Dual-mode sensor based on atomically dispersed CuCu-N2O2 site in a Salen-based covalent-organic framework for electrochemical-colorimetric detection of dopamine and uric acid.
We have developed a novel electrochemical-colorimetric dual-modal sensor based on a metallosalen-based covalent organic framework (Salen-COF) for separate electrochemical quantification of uric acid (UA) and dopamine (DA) and colorimetric screening of their total amount. The Salen-COF was synthesized via a Schiff-base...
