J022043 Terahertz time domain spectroscopy for noninvasive evaluation of regenerative tissue

Abstract

When bringing regenerated cartilage into practical use, due to its piece to piece property difference, non-invasive assessment methods should be developed. We intended to achieve non-invasive assessment of cartilage by applying terahertz technology. The purpose of this research is to clarify the relation between cartilage characteristics and terahertz spectra.In this paper, we clarified the relation between the amount of free/bond water in cartilage, which is one of the factors that decides the characteristic of cartilage, and absorbance of the terahertz wave by measuring natural bovine cartilage, natural bovine cartilage treated with enzyme and gel components of cartilage which are gelatin gel and chondroitin sulfate gel.
