Three-dimensional (3D) printing technol. has attracted great attention for prototyping different electrochem. sensor devices. However, chiral recognition remains a crucial challenge for electrochem. sensors with similar physicochem. properties such as enantiomers. In this work, a magnetic covalent organic framework (COF) and bovine serum albumin (BSA) (as the chiral surface) functionalized 3D-printed electrochem. chiral sensor is reported for the first time. The characterization of the chiral biomol.-COF 3D-printed constructure was performed by SEM (SEM), XPS, and energy-dispersive X-ray spectroscopy (EDX). A tryptophan (Trp) enantiomer was chosen as the model chiral mol. to estimate the chiral recognition ability of the magnetic COF and BSA-based 3DE (Fe3O4@COF@BSA/3DE). We have demonstrated that the Fe3O4@COF@BSA/3DE exhibited excellent chiral recognition to L-Trp as compared to D-Trp. The chiral protein-COF sensing interface was used to determine the concentration of L-Trp in a racemic mixture of D-Trp and L-Trp. This strategy of on-demand fabrication of 3D-printed protein-COF-modified electrodes opens up new approaches for enantiomer recognition. In the experiment, the researchers used many compounds, for example, H-D-Trp-OH (cas: 153-94-6Electric Literature of C11H12N2O2).
