In the Czech Republic, a paper was invented that destroys bacteria and viruses that enter its surface, including particles of coronavirus, reported by the Czech agency ČTK. Scientists hope that their invention can be used in the manufacture of banknotes and documents.
The paper is impregnated with special chemicals with zinc and silver nanoparticles. They kill viruses, bacteria and yeast, but remain safe for human skin. "Within one minute, 99% of microbes disappear from its surface, " said one of the developers, Jiri Sobek. According to him, the development was carried out for several years.
“The main function that begins to kill bacteria and viruses after contact is twofold. The bacteria are killed within one minute with an efficiency of over 99 percent. Complete inactivation occurs. For covid viruses, tests have confirmed that after 10 minutes this is about 70 percent and after 30 minutes all the covid on the surface will be inactivated, ”the scientist explained.
Thanks to additional modification, such paper can even destroy particles of a new type of coronavirus that hit its surface.
“And we are ready to produce from 10 to 20 thousand tons of paper,” the scientist concluded.
In the near future, the Czech Republic plans to produce the first 10 tons of such paper.
