The application of Raman spectroscopy for control
of connective tissues under IR laser irradiation
Abstract
Raman spectra of intact and
treated by medium intensity IR laser radiation samples of cartilage and fibrous
connective tissues (FCT) are presented in this article. It was shown that a main difference between spectra of cartilage and FCT
is observed in the region of piranose circles’ vibrations (960-1175cM’).
Changes of relative intensities and frequencies of Amid 1 and III bands at
different humidity and after laser treatment are discussed. A difference between Raman spectra of intact and
irradiated by laser tissue samples is related to the collagen denaturation and
to the change of the conformational state of polysaccharides chains.
