Paper Abstract

We demonstrate how optical trapping and manipulation can be used to assemble microstructures. The microstructures we show being automatically recognized and manipulated are produced using the two-photon polymerization (2PP) technique with submicron resolution. In this work, we show identical shape-complementary puzzle pieces being manipulated in a fluidic environment forming space-filling tessellations. By implementation of image analysis to detect the puzzle pieces, we developed a system capable of assembling a puzzle with no user interaction required. This allows for automatic gathering of sparsely scattered objects by optical trapping when combined with a computer controlled motorized sample stage.
