Effects of a Pseudophysiological Environment on the Elastic and Viscoelastic Properties of Collagen Gels
Relaxation moduli of ring-shaped collagen gels as a function of temperature (experiments performed either at 23°C or 37°C), hydration (either with or without a PBS solution), and mechanical preconditioning (either with or without mechanical preconditioning PC). , , and are, respectively, the elastic and the viscous moduli of the gels considered in the viscoelastic model. The sum of all 3 moduli is the instantaneous linear modulus at a strain of 10%. Values are expressed as mean standard error. Significance: *; **; ***.
