Science and Technology: Masks have become an integral part of the common man for survival since the onset of Covid two years ago. IT has become an essential to prevent the spread of COVID-19, and scientists across the globe are busy employing technical advancements to make them even more effective at minimizing transmissions.
Scientists from Japan
In a recent development researchers in Japan are utilizing ostrich antibodies to detect COVID-19 under UV light, which they believe will aid in the detection of asymptomatic patients. The mask was designed by Yasuhiro Tsukamoto and his colleagues at Kyoto Prefectural University based on prior research that demonstrated ostriches have a high resistance to COVID-19.
The mask’s filter is coated with ostrich antibodies. Test subjects wore the masks for eight hours before spraying the filters with a chemical that glows under ultraviolet light if the virus is present. The team is currently working on face masks that will glow automatically.
Scientists from UK
Scientists in the UK are using nanomaterials to create a face mask designed to stop the spread of COVID-19. The team at the University of Aberdeen is using a technology called microfluidics, which would harness silver nanoparticles to turn masks into active barriers and increase their efficiency.
Scientists from US
In another attempt to bolster what masks can do, engineers at MIT and Harvard University are embedding small, disposable sensors to detect COVID-19. The face mask aims to diagnose the wearer with COVID-19 within 90 minutes, based on freeze-dried cellular machinery that the team has previously used for paper diagnostics of Ebola and Zika. The results are displayed on the inside of the mask for user privacy. In a new study, the researchers incorporated the sensors, not just into face masks, but also lab coats.
