Scientists have invented particles able to keep a person alive even if they are unable to breath.
The breakthrough treatment works by oxygenating the blood through an injection that can keep someone alive for up to 30 minutes even if they are unable to breath at all and could save thousands of lives. The injected particles contain oxygen within a layer of natural molecules known as lipids. Previous attempts at developing a treatment of this nature had failed because the injections caused a gas embolism rather than oxygenation of the cells.
"We have engineered around this problem by packaging the gas into small, deformable particles," said scientist John Kheir. "They dramatically increase the surface area for gas exchange and are able to squeeze through capillaries where free gas would get stuck."
"This may seem like something out of a science fiction movie: researchers have designed microparticles that can be injected directly into the bloodstream to quickly oxygenate your body, even if you can't breathe anymore."
