Collagen as the most abundant protein in mammals plays a crucial role in biochemical and biomechanical processes; especially the biomechanical significance is phenomenal. The inner organization and shape of fibres reflects the mechanical properties of the tissue [1], though the precise mechanisms in vivo remain unravelled.Visualisation methods such as confocal laser scanning microscopy together with polarisation microscopy and second harmonic generation (SHG) enable one to display certain non-centrosymmetric molecular structures.
This approach seems to be ideal as a supporting method for loading tests.
