Polarization Effects in SHG of Collagen

摘要

The polarization dependence of the second harmonic emission of purified in-vitro reconstituted fibrils of collagen has been examined. The results confirmed the quasi-hexagonal crystalline structure within the fibrils. Interesting different polarization behaviours were seen between collagen types Ⅰ and Ⅱ, which can be utilized as an experimental technique for differentiation.
