Passing from millimeter to micrometer scale, the traditional pick and place method for assembling large amount of compounds be- comes difficult and time consuming. At micrometer scale it is then very important to have other assembling methods. This work presents the ability to perform selective and pairwise serial self-assembly of more than 500 immersed compounds, using hydropho- bic interaction [1]. To show the selectivity of the assembly, bicolor 100 μm SU-8 filled cylinders have been fabricated by photolithogra- phy techniques. Inducing selective hydrophilic interaction, a yield higher than 60% of correctly assembled parts has been achieved.
