| Research Abstract |
We demonstrated autofluorescence lifetime imaging of human colon specimens obtained by endoscopic mucosal resection (EMR). As a result, we found that there is a difference of fluorescence lifetime using the excitation and fluorescence wavelengths of FAD (flavin adenine dinucleotide) between normal and adenoma regions. This difference is mainly caused by fluorescence from mucosal epithelial intracellular molecules. Autofluorescence lifetime imaging would be a promising and practical method having potential for the detection of colon adenoma targeting intracellular environments.
