Abstract:A CMOF is synthesized by the grafting of carboxymethyl-β-CD to l-histidine-functionalized ZIF-8, which is used for the discrimination of tryptophan enantiomers.
A electrochemical sensor for the chiral recognition of Trp based on chiral polyaniline (D-PANI) and β-CD-MOF was designed. It displayed higher affinity of L-Trp, and the oxidation peak current ratio (IL/ID) of DPV could be reached at 2.26.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
