Raman study of the shockwave effect on collagens.

The Raman spectra (1800-200 cm(-1)) of isolated dried collagen types I and III were recorded at different times after shockwave (SW) application in aqueous media. SWs were applied in a single session. One week after the SW application the vibrational data analysis indicates changes in the conformation of the collagens; orientational changes are also inferred. During the next three weeks collagens tended to recover the conformation and orientation existing before SW application.
