3.4. Mechanical properties
The incorporation of yeast into the hydrogel changes the swelling capacity. Thus, if the structure of hydrogels capsules suffers an alteration because of the increases in the cell loading, the mechanical properties could also be modified. Elastic modulus (E) was determined by uniaxial compression from stress and strain plot (Fig. 3). The E data for the different pAAm-Sc gels are described in Table 3.
