Figure 3: Bubble-particle interaction.
From: A microscopic steam engine implemented in an optical tweezer
(a) Selected frames of a 3-μm particle before, during the explosion and after recorded at 300,000 fps. Scale bar, 10 μm. (b) Selected frames for a 1-μm particle recorded at 500,000 fps before, during and after the explosion, these videos were not used to extract trajectories. Scale bar, 5 μm. (c) Parameters to describe the interaction between the bubble and the microparticle. δ′ is the distance from the centre of the particle to the origin of the bubble, which is at the surface of the particle.
