Characterization of microdevices in Caco-2 cells. A) Biocompatibility studies of the microdevices on Caco-2 cells with a propidium iodide (dead) stain, PrestoBlue assay, and ATP assay (two-tailed t-test, Mean ± SD; n=3). B) Fluorescence confocal images (10X) of microdevice (Scale Bar =100 μm) and of microdevices incubated for 3 hours on Caco-2 cells grown on transwells for 3 weeks (60X) showing the microdevices in brightfield (BF), DAPI nucleus (blue) stain, and phalloidin actin (green) (representative image of n=3 wells). Scale Bar =10 μm.
