Researchers at the Division of Nanotechnology and Functional Materials, Uppsala University have developed a paper filter, which can remove virus particles with an efficiency matching that of the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nanofibers, directly derived from nature.
This seems like it is a HUGE development. If we can screen out viruses, does that mean we can start filtering blood or use these filters in medical implants to recover from or prevent viruses from affecting the body? The researchers of this ten year project have something to be proud of indeed!
