Figure 2: Mass of Alginate Film Based on Deposition Time- Three different alginate viscosity grades were electrophoretically deposited on thin rectangular substrates. By 1 minute, the LV and MV grade alginates did not have dissimilar masses (p-value = 0.163) and were 1.31 ± 0.02 g. The HV grade alginate was heavier (p-value = 0.011) with a mass of 1.47 ± 0.03g. By 10 minutes, the LV and MV grade gels were similar (p-value = 0.347) with masses of 8.33 ± 0.15 g. The HV grade alginate was then lighter (p –value = 0.010) than the other gels with a mass of 7.60 ± 0.16 g. The Sarkar model was used to fit the LV (R2 = 0.9914), MV (R2 = 0.9886) and HV (R2 = 0.9907) data. Error bars are in S.E.M., n = 3.
