From: Molecular mapping of periodontal tissues using infrared microspectroscopy
IR chemical mappings in periodontal tissue. Four major molecular distributions (total protein; lipid; DNA; collagen) in periodontal tissue (A-D) were generated based on the corresponding IR molecular signals. Higher concentrations of the major cellular components were observed in the periodontal epithelium (A-C) whereas higher amounts of collagen exist in the connective tissue (D), as expected.
