Three-dimensional polymeric microtiles for optically-tracked fluidic self-assembly
We present innovative 3D polymeric microtiles for fluidic self-assembly. The design accounts for the unpredictable orientation of the microtiles in liquid. A thick Cu sacrificial layer is used for independent patterning of stacked SU-8 layers. The process can be upscaled to large substrates for batch production of microtiles. This work is functional toward studies of SA dynamics at microscale.
