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. Kꚺ⚢힝 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)64âand other molecules through the channels in TiO2nanotubes. This fabricated permselective membrane using K a trigger may set light to the field of biosensing, drug-release, ion exchange membrane and so on. [ABSTRACT FROM AUTHOR] |
