Abstract :
Collagen sheets were prepared from sea cucumber and their absorption properties were measured at terahertz frequencies. Adding salt to the collagen sheet caused the spectral shape to noticeably change at around 170 cm-1, and this change was related to the contraction and condensation of collagen fibers.
