Scientists have developed a new microparticle filled with oxygen that can be injected into the blood stream, keeping you alive even if you can’t intake air into your lungs. The microparticles are actually tiny capsules (2-4 micrometers tiny) made of a single layer of lipids surrounding a small bubble of oxygen gas. The capsule is suspended in a liquid so that the bubbles don’t get any bigger (which would make them deadly, FYI).
