Sometimes simplicity is best. Two Northwestern University
researchers have discovered a remarkably easy way to make nanofluidic devices:
using paper and scissors. And they can cut a device into any shape and size
they want, 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 the devices promising for use in batteries and new systems
for water purification, harvesting energy and DNA sorting.
