Commercial reverse osmosis (RO) membrane technology has advanced only incrementally over the last 30 years.

However, Biomimetic Membranes for Water Purification, developed by Albuquerque-based Sandia National Laboratories and the University of New Mexico, represent a new approach to biomimetic membrane design and fabrication.

The invention uses self-assembly and atomic layer deposition (ALD) to advance the field of membrane technology for water filtration.
