Emission spectra of colonic tissue and endogenous fluorophores.
Autofluorescence emission spectra of normal, adenomatous, and malignant tissues of the colon were compared to that of known fluorophores to indicate the possible causes of tissue fluorescence. DataExpand

Role of basement membrane collagen and elastin in the autofluorescence spectra of the colon.
BACKGROUND Autofluoresence can be used to detect neoplasia in the colon. Two known fluorophores, collagen and elastin, are probably partly responsible for colonic emission spectra. Their contributionExpand
