Alginate polymer and hydrogel characterization: Shear elastic modulus data represented as average±SEM from three or more independent measurements

alginate Mw (kDa) PDI G’(Pa)
3% 418 2.07 3010±84a
1.5% 418 2.07 1300±129b
0.7% 418 2.07 203±13c
ox 293 2.38 629±62c
irr 83 2.00 384±77c

Mw=weight average molar mass, G’=shear elastic modulus, kDa=kilodaltons, PDI=polydispersity, Pa=pascals. In this and other tables and figures, 3% = 3% untreated, 1.5% = 1.5% untreated, 0.7% = 0.7% untreated, ox = oxidized (1.5% w/v), and irr = irradiated (1.5% w/v). Significant differences between conditions are indicated by different letters (p<0.05)
