Ultrafast active water pump driven by terahertz electric fields
Qilin Zhang, Rong-Yao Yang, Chunlei Wang, Jun Hu
Abstract
A terahertz electric field (TEF) is employed to stimulate an active pump for water transportation by a bias applied in a nanochannel under no external pressure gradient. The excellent pumping ability is attributed to the resonance coupling between the TEF and water molecules. This proposed TEF-driven pump design will offer a guide in polar molecule transport through artificial or biological nanochannels, particularly in a controllable, noncontact, and large-scale process.
