Figure 2

(a) Reconstructed surface images of plasma-treated and untreated HSA-DMEM/F12 hydrogels with interferometry. Plasma-treated surfaces are significantly rougher than untreated surfaces, Ra values expressed as mean ± standard deviation, ***p < 0.001. (b) Stress–strain curves of plasma-treated and untreated HSA-DMEM/F12 hydrogels with the calculated Young's moduli. Values represent mean ± standard error. No statistical difference was detected between both groups.
