Fig. 4: Dynamic manipulation of multiple particles via STREAM.
From: Streaming-based Tweezers for Routing, Engineering, and Manipulation of multiparticles: STREAM
a Schematics of manipulation of a pair of particles along a square-shaped route. b and c The actual trapped position of the two particles in the x and y direction, respectively. The dotted lines show the target position in both the x and y directions. d Spatial error with two directions added up at different steps, T, for each particle, respectively. e Time-stacked result for each particle in a route consisting of 21 points. The two arrows with different colors show the direction of movement of both particles, respectively. f Images (i–vii) showing multiple particles trapping at steps 1, 4, 7, 10, 13, 16, and 19, respectively. Scale bar: 6 mm
