Robust bubbles of gas encapsulated in a microsphere–liquid shell could trap gases

Extremely strong and stable bubbles have been created by trapping a small amount of gas in a liquid film surround by polymer microparticles.1 The researchers have dubbed the new bubbles ‘gas marbles’ and say that they could be used as tiny chemical reactors, to stabilise foams or to capture toxic gases.
