To preserve samples for a longer period, Scientists from the University of Louisville, USA, used ultrasound and a special natural preservative. About the work of scientists writes Eurek Alert. The publication explains that scientists used ultrasound to create pores in the blood cells that would allow the introduction of special molecules there to preserve red blood cells for a long time.. Molecules of trehalose, a natural sugar that some organisms produce to survive drought, have become this preservative.. Using ultrasound, trehalose penetrated cell membranes, after which the samples could be dried for further storage. “This will allow storing blood samples in“ dried ”form at room temperature for several years, so that they can be used in regions with limited access to donated blood,” the study authors report.. The technology will provide biomaterial not only to remote regions and ambulance services, but also to use it during long space missions, the authors are sure. Earlier it was reported that in the UK, scientists are studying the possibility of using the blood of patients with coronavirus to help infected. News from Telegram.
