Viruses Removed by Nano-Paper Filter

Virus particles are very peculiar objects - tiny (about thousand times thinner than a human hair) yet mighty. Viruses can only replicate in living cells but once the cells become infected the viruses can turn out to be extremely pathogenic. Viruses can actively cause diseases on their own or even transform healthy cells to malignant tumors. 

Uppsala University, Nanotechnology and Functional Materials, have come up with a paper filter that can remove virus particles as effectively as the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nano-fibers, directly derived from nature. These nano-cellulose materials have a high surface area, which eventually enable the scientists to tailor the pore size distribution of their  paper precisely in the range desirable for virus filtration.
