Faster optical delivery of self-arranged multi-particle cluster

Rectification of random motion of particle a motional array of optical traps created by interference of two counter-propagating evanescent waves, i.e. in a so called optical conveyor belt (OCB), leads to the directed and controlled motion of such a particle. Particle clusters are formed if more than one particle enters the OCB. The particles were optically self-arranged into a linear chain with well-separated distances between them. We observed a significant increase in the delivery speed of the whole structure as the number of particles in the chain increased. This could provide faster sample delivery in microfluidic systems. We quantified the contributions to the speed enhancement caused by the optical and hydrodynamical interactions between the particles.
