Storage modulus of alginate gels as a function of alginate fraction in solution or particulate. Final storage modulus (A) and half time (t
) calculated from fitted oscillatory rheology curves, as a function of the fraction of sodium alginate (F
g = 0.7 and M
= 219 kDa) in a mixture with Sr alginate or Ca alginate. The total alginate concentration was always 2.0%. Bars demonstrating standard error of the mean are indicated when exceeding the symbols.
