报告摘要:Controlling active transport of water through membrane channels is essential for biological processes and advanced nanofluidic devices. Despite advancements in water nanopump design using techniques like short-range invasion and subnanometer-level control, challenges remain in facilely and remotely realizing massive waters active transport. Herein, we propose an ultrahigh-flux nanopump, powered by frequency-specific terahertz stimulation, capable of unidirectionally transporting massive water through asymmetric-wettability membrane channels at room temperature without any external pressure. Impressively, it can outperform existing advanced reverse osmotic membranes by up to ten thousand times in flux performance. The key physics behind this terahertz-powered water nanopump is revealed to be the energy flow resulting from the asymmetric optical absorption of water.
