Sheet that can remove viruses from water created
Sweden-based scientists have created a paper sheet, mille-feuille filter, that can filter-out viruses from water. It is made of cellulose nanofibers and has a layered internal architecture resembling that of mille-feuille, a French puff pastry. "Our goal is to develop a filter paper that can remove even the toughest viruses from water as easily as brewing coffee", a researcher said.
