Figure 2: Characterization of differentially crosslinked films.
From: Differentially photo-crosslinked polymers enable self-assembling microfluidics
(a) Relative fluorescence intensity profiles of conditioned and sectioned SU-8 films that were ultraviolet exposed for (top) 80 mJ cm−2 (32–42% of manufacturer's suggested energy) and (bottom) 300 mJ cm−2 (>100% of suggested energy). Plots are averages of three lines. Shaded regions denote the standard deviation. (b) A plot of the average radius of curvature versus ultraviolet exposure energy of free-floating, self-assembled 1.5 mm×0.15 mm beams of varying film thickness. n is 6 (4 for 1.1 μm) and bars denote standard deviations.
