Japanese Scientists Develop Glowing Masks To Detect Coronavirus (kyodonews.net) 89

Posted by msmash from the closer-look dept.
A team of scientists at a university in western Japan has developed masks that glow when exposed to ultraviolet light if they contain traces of the coronavirus, using antibodies extracted from ostrich eggs. From a report: The team at Kyoto Prefectural University, headed by its president, Yasuhiro Tsukamoto, 52, hopes the masks will offer users an easy way to test whether they have contracted the virus. With testing continuing to put them into practical use, the team aims to gain government approval to sell the masks possibly next year. Ostriches are capable of producing several different kinds of antibody, or proteins that neutralize foreign entities in the body. In February last year, the team injected an inactive and non-threatening form of the coronavirus into female ostriches, successfully extracting a large quantity of antibodies from the eggs that they laid.

    It would be a lot easier to detect if it just changed color, period. The requirement of ultraviolet light means you either need to be outside or have an ultraviolet light present.

    Don't get me wrong though, it's a lot better than nothing (aka, the current situation).

      And I'm guessing the rest of the lack of clarity is due to the FP pressure. So the next question is how you think this mask is better? If the mask actually works as an anti-Covid-19 mask, then the color change only tells you the mask has been exposed, but nothing about whether you're ill.

        Pretty sure these masks would be much more expensive than the transparent masks I actually want. I'd be willing to pay a reasonable premium for transparency, especially if the mask is reusable, preferably washable, but I'm confident that the masks of this article would be MUCH more expensive. And no, I'm not encouraged by the idea of wearing the same mask until it changes color.

          Masks rely on a mess of a micron fine fibers to block particles, and you need a significant thickness of this material to achieve the target (ex: N95) rating.

          So you have a relatively thick material that is irregular, with details about the size of the wavelength of visible light, good luck making it transparent.

        I don't think the fabric to make the mask you want exists. What could be done is sort of a "mini-helmet" with two vent tubes, one for exhale, one for inhale. But you'd need to power that, though it wouldn't need much power. One-way vents are easy with flap valves, but the amount of air you need to force through is uncertain, and if you want to filter the intake (I envision it as around the back of the nect somewhere) you will need enough power to overcome that additional resistance.
