FIG. 1.

(a) Fabrication process of microsystems integrating i-PDMS microstructures: (A) SU-8 spin-coating on a glass substrate, (B) SU-8 photolithography and development, (C) i-PDMS deposition and curing, (D) pouring of PDMS and curing, (E) Demolding of the system and punching of the inlets and outlets, (F) side view, and (G) top view of the final microsystem. (b) Schematic side view of the experimental setup presenting the optimized configuration of the permanent magnets regarding to the microsystem. (c) Picture of the microchannel mounted with the magnets. The close-up allows distinguishing the i-PDMS diamond-like microstructures.
