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 contribution… Expand
