Covalent organic frameworks (COFs) have drawn great interest in electrochemical sensing. However, most are integrated as enrichment units or reaction carriers and co-modified with metal nanomaterials. Few studies use the single pristine COFs an signal amplifier. Aza-fuzed π-conjugated exhibit exceptional enhancement effective electron transport layer for sensing applications. In this work, different conductive aza-fuzed were optimized by synthetic engineering. Among them, 2D crystalline COF4 highest conductivity (240% via bare electrodes) was used to modify screen printing carbon electrode construct a portable molecularly imprinted biosensor point-of-care glutathione detection. Compared conventional strategy of co-modifing gold nanoparticles, sensor exhibited excellent detection performance better selectivity thiol interferents. Conductive combining polymer provide promising constructing low-cost, easy fabrication operation, highly sensitive selective biosensors.
