Fig. 17.2 — Hydrodynamic interactions between trapped colloidal particles
(a) Cross-correlation in the position fluctuations of two trapped colloidal particles for three different particle separations. The lines through the data points are the expected form of the cross-correlation using a theory based on the hydrodynamic coupling described in the text. (b) Pairing of particles driven around the circumference of a ring-shaped vortex beam trap. (c) Hydrodynamic synchronisation of a pair of optically trapped oscillators.
