Figure 4
Diffusion coefficients of FITC-dextrans in PEG-DA (20kDa) hydrogels at three different swelling ratios (Squares: ϕ=0.03 , circles: ϕ=0.05 , triangles: ϕ=0.08 ) do not deviate considerably at different temperatures (filled symbols: T=25 °C, open symbols: T=37 °C). Linear fitting analyses based on equation (4) are shown for the data measured at T=25°C. Error bars represent +/− SD.
