英文摘要	In the present work, we demonstrated a novel type of artificial K+-gated ion channels based on titania nanotubes loaded with Au nanoparticles and G-rich DNA composite structure. K+ promoted conformational change of G-rich DNA from flexible chain to rigid quadruplex, which provided a blocking effect for the transport of anions such as Fe(CN)(6)(4-) and other molecules through the channels in TiO2 nanotubes. This fabricated permselective membrane using K+ as a trigger may set light to the field of biosensing, drug-release, ion exchange membrane and so on.; Chemistry, Physical; Physics, Atomic, Molecular & Chemical; SCI(E); PubMed; 9; ARTICLE; 34; 9989-9992; 12
