要旨

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)64− 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.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
