Biomimetic Multifunctional Nanochannels Based on the Asymmetric Wettability of Heterogeneous Nanowire Membranes

摘要

Ionic transport through cell membranes which are highly heterogeneous structured and rich in massive channels is crucially important in many fundamental biological processes. Recent years, many works have been focused on the construction of charged nanopores or nanochannels with sizes limited to 100 nm, aiming to mimic the multiple function in organism channels, such as transport, selectivity and gating. Compared with the biological counterpart, the artificial membrane is more flexible in size, shape, enhanced in mechanical strength and stability, and variegated in response to external stimuli.
