A paper sheet made by scientists at Uppsala University in Uppsala, Sweden, can remove resistant viruses from water, according to an article on the Infection Control Today website.
The mille-feuille filter is made of cellulose nanofibers and resembles the French pastry mille-feuille.
'With a filter material directly from nature, and by using simple production methods, we believe that our filter paper can become the affordable global water filtration solution and help save lives. Our goal is to develop a filter paper that can remove even the toughest viruses from water as easily as brewing coffee', said Albert Mihranyan, professor of nanotechnology at Uppsala University, who heads the study.
Water-borne infections are among the global causes for mortality, especially in children under age of five.
