Paper-and-scissors technique rocks the nano world: Future nanofluidic devices for batteries, water purification systems

Sometimes simplicity is best. Researchers have discovered an easy way to make nanofluidic devices: using paper and scissors. And they can cut a device into any shape and size, adding to the method's versatility. Nanofluidic devices are attractive because their thin channels can transport ions -- and with them a higher than normal electric current -- making them promising for use in batteries and new systems for water purification, harvesting energy and DNA sorting.
