This effect was achieved thanks to the treatment of the removable mask filter with a special fluorescent dye.

Japanese scientists from Kyoto Prefectural University have developed a protective mask that glows under ultraviolet light if there are traces of coronavirus on it. According to the Kyodo news agency, this effect was achieved thanks to the processing of the removable mask filter with a special fluorescent dye.

The composition of the dye includes antibodies obtained from ostrich eggs that affect the coronavirus. In February last year, scientists introduced an inactive and safe form of coronavirus to female ostriches and extracted a large number of antibodies from their eggs.

“We can mass-produce antibodies from eggs of ostriches at a low price. In the future, I want to turn this into a simple testing kit that everyone can use,” Yasuhiro Tsukamoto, head of the research group, was quoted as saying by the agency.

32 patients with coronavirus participated in the tests of luminous masks. All the masks they wore glowed under ultraviolet light. Over time, when the viral load decreased, the glow disappeared. Tsukamoto’s team plans to expand the experiment by involving 150 participants.
