Spherical nanoindentation of polyacrylamide hydrogels by the Bioindenter

Hydrogels are very compliant materials suitable for tissue engineering in various areas of biological and clinical research. Appropriate and effective application of hydrogels for specific cellular regeneration often requires precise knowledge of their mechanical properties.

The present application report focuses on the measurements of mechanical deformation and creep properties of polyacrylamide hydrogels using the Anton Paar Bioindenter.

Four concentrations of polyacrylamide gel were tested under four different loading rates to study the mechanical response of the material. This work contributes to the understanding the results of instrumented indentation of extremely compliant materials with respect to their viscoelastic properties.
