Japanese researchers have developed masks in which ostrich antibodies are placed, while in case the virus is present in the mask, ultraviolet light is turned on, after being sprayed with a chemical.
According to foreign media, the discovery, by Yasuhiro Tsukamato and his team at Kyoto Prefectural University in western Japan, could provide low-cost testing for the virus at home.
Scientists began creating a mask filter with ostrich antibodies that target the virus, based on previous research showing that birds had strong resistance to disease.
In a small study, test subjects wore masks and after eight hours the filters were removed and sprayed with a chemical that glows under ultraviolet light if the virus is present.
Filters worn by people infected with COVID-19 shone around the nose and mouth.
The team hopes to further develop the masks so that they glow automatically, without special lighting, if the virus is detected.
