Ben-Gurion U. researchers develop membranes that remove viruses from drinking water

(American Associates, Ben-Gurion University of the Negev) The 'zwitterionic polymer hydrogel' repels the viruses from approaching and passing through the membrane. It contains both positive and negative charges and improves efficiency by weakening virus accumulation on the modified filter surface. The result was a significantly higher rate of removal of waterborne viruses, including human norovirus and adenovirus.
