Abstract:Biological ion channels exhibit switchable cation transport with ultrahigh selectivity for efficient energy conversion, such as Ca 2+ -activated TRPM4 channels tuned by cation−π interactions, but achieving an analogous highly selective function is challenging in artificial nanochannels. Here, we design a TRPM4inspired cation-selective nanochannel (CN) assembled by two poly(ether sulfone)s, respectively, with sulfonate acid and indole moieties, which act as cation-selective activators to manage Na + / Cl − sele… Show more
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.
