Membrane Sorts Single Molecules

A new, extremely thin membrane developed at the University of Rochester, can sort single molecules. The 50-atom thick filter can withstand surprisingly high pressuresand may be a key to better separation of blood proteins for dialysispatients, speeding ion exchange in fuel cells, creating a newenvironment for growing neurological stem cells, and purifying air andwater in […]

NanofilterA new, extremely thin membrane developed at the University of Rochester, can sort single molecules.

The 50-atom thick filter can withstand surprisingly high pressuresand may be a key to better separation of blood proteins for dialysispatients, speeding ion exchange in fuel cells, creating a newenvironment for growing neurological stem cells, and purifying air andwater in hospitals and clean-rooms at the nanoscopic level.

At more than 4,000 times thinner than a human hair, the newbarely-there membrane is thousands of times thinner than similarfilters in use today.

The study was published on Valentine's day in Nature.
