Analysis and control of molecule and ion transport in nanopores

Recent advances in synthesis, measurement, and analysis techniques of nanofluidic systems have allowed ion transport to be systematically explored in narrow, confined channels with dimensions of less than 10 nm. In such small dimensions, anomalous ion transport can be observed. The studies of ion transport in sub-10 nm fluidic channels provide opportunities to explore artificial ion channels that can mimic protein ion channels in physiological cells or proton exchange membranes in high energy density fuel cells. In this study, the measurement and analysis of ion transport in well-dimensioned mesoporous silica by applying electric fields were conducted in order to effectively apply them to various technologies.
