Fabrication of Metal-Free Covalent Organic Frameworks (COF)-Based Nanozyme ETTATFB-COOH via the Doebner Reaction for Dual-Channel Sensing of Aristolochic Acid A.
Covalent organic frameworks (COF) have attracted considerable attention in the fields of sensing and catalysis owing to their unique structural and physicochemical properties. However, their practical applications remain limited by insufficient stability and the lack of integrated multifunctionality. In this work, ETTA...
