(A) Schematic view of the hybrid microdevice made from two circular loading chambers (diameter: 2.5 mm) connected by parallel rectangular channels (width: 14 μm, height: 8 μm). Soybean oil droplets are inserted within the channels and make a deformable obstacle to the migration of HL-60 cells. (B) Confocal microscopy picture of PDMS channels containing oil droplets stained with Nile Red dye. Scale bar: 30 μm. (C) Top view and 3D reconstructed side view of a droplet blocked in a micro channel. Scale bar: 10 μm.
