Abstract

The tissue microenvironment has received significant attention in recent decades since the revelation that it contains biophysical and biochemical cues that influence critical cellular behaviour such as proliferation,differentiation, migrations and survival. In this thesis, atomic force microscopy is used on a simple type I collagen model. The data shows that current assumptions in the literature attributing the bimodal distribution of modulus values found in tissue to proteoglycan and collagen may not be valid. The data suggests that the bimodal values are both related to collagen. The effect of glutaraldehyde cross-linking on the nanomechanical profile was examined, revealing a significant distortion. Infrared spectroscopy was used to further investigate the changes of the chemical environment due to cross-linking.
