Carbon Nanotube-based

Nanofluidic Pump

Carbon nanotubes (CNTs) are a type of graphene: a wonder-material with superconductivity and superstrength. Here, we use these remarkable properties to demonstrate CNTs as nanofluidic pumps. Above, the orange arrows show how an electrical signal applied to the outer CNT shell can pump ions through the inner core. In filtration, we could use this capability to remove undesired materials; in biomimetic engineering, it could contribute to controllable membranes and artificial organs. These findings also develop our understanding of how to exploit nanoscale effects in fluidic applications. We published this research in Nano Letters with the paper available here.
