A team of researchers at Caltech has developed a way to capture on film the superfast propulsive motion of Brownian objects, particularly those at the nanoscale. In their paper published on the open-access site Science Advances, the team describes using four-dimensional electron microscopy techniques to capture real-time imagery of gold nanoparticles as they diffused in a liquid.
