Nature provides a huge range of biological materials with various smart functions over millions of years of evolution and serves as a big source of bio-inspiration for biomimetic materials. From small biological ion channels to large oil pipelines, the structures with "Pore" and "Channel" are everywhere. Ion channels existing in living organisms play a significant role in maintaining balanced physiological conditions and serve as “smart” gates to ensure selective ionic transport. Pipelines, which are commonly used in chemical industry, food industry, agriculture, and energy-petroleum transportation, can be treated as macro-scale channels. Multi-scale pore and channel systems have been intensively explored and contributed to new developments in materials science, membrane science and technology, or micro/nanotechnology for analytical, biomedical, and energy applications. Stimulated by the achievements and the even larger potential of multiscale pore and channel systems, increasing research activities are devoted to important aspects such as energy saving, anti-fouling, anti-corrosion, and anti-blocking functionalities, switch ability and controllability integration of various functionalities, and good stability in such confined space. This talk describes the key ideas and presents some of the most recent device examples, including bioinspired and smart multiscale pore/channel systems, especially building bio-inspired liquid-based gating systems for bringing a new generation of design ideas of membrane separation technology; and bio-inspired stimuli responsive micro/nanochannel systems for biomedical applications. The presentation will feature the most recent results from the group, with highlights in published and unpublished work over the last three months.
