Abstract:Ion transport plays an important role in various biological processes because of the ability of ions to move rapidly in biological ion channel‐confined spaces. For example, rapid proton transport in ATPases is attributed to confined channel spaces and conjugated sites. According to molecular dynamics simulations, the confined spaces and conjugated sites in nanochannels can enhance ion transport. Herein, it is demonstrated that the ATPase‐like structures of sulfonic acid‐modified covalent organic framework nano… Show more
“…Nano- and sub-nanochannels in proteins exist in the confined state that, together with binding sites, provide an orderly arrangement of ions. 25,26 This protein confinement between two lipid bilayer membranes leads to facilitating fast ion transportation. The synthetic polyelectrolytes and natural proteins combine high affinity to particular ions with the ability to exclude other undesired permeants.…”
The device based on polyelectrolyte–graphene oxide membranes demonstrates neuromorphic functions successfully applied with nanochannel ion interactions, resulting in a short-term memory effect.
