Storage and loss moduli were measured for the frequencies between 0.01 to 20 Hz. The representative data (mean± standard deviation) at 1 and 10 Hz is shown (Col-I: collagen type I, Col-III: collagen type III and Col-I&III: the simultaneous presence of Col-I and Col-III; G1 and G2 represent 2% and 1% final glycol-chitosan concentration, respectively.).
