AUTOFLUORESCENCE OPTICAL BIOPSY. Autofluorescence AF) is an intrinsic diagnostic parameter due to the intratissue presence of endogenous fluorophores acting as biomarkers. Under suitable conditions of excitation light. the AF emission properties depend on nature, amount, physical-chemical state, intratissue distribution and microenvironment of endogenous fluorophores, and on the optical of the tissues (reflection; absorption, scatter), in close dependence on the metabolic and morphofunctional state of biological substrates. On these basis, AF optical biopsy can provide information in real time on the physiological state, functional changes of pathologcal alterations of tissues and organs, not requiring removal of tissue samples and without the perturbation caused by the administration of exogenous markers. AF optical biopsy is thus an innovative procedure receiving increasing attention at international level, as a non invasive or minimally invasive diagnostic approach based on the light-matter interaction.
In this field, experience has been acquired on the AF analysis of cells and tissues, mainly as to diagnosis in oncology and the monitoring of organs functionality. Studies are performed on hepatic tissue, as to the monitoring of the redox state and of the organ functionality under normal and alterated conditions (transplantation phases, disorders and metabolic alterations), based on the characterization of well assessed endogenous fluorophores (i.e. NAD(P)H, flavins, vitamin A, collagen) and endogeous fluorophores currently under study (I.e. biliary pigments -biliverdin, bilirubin, porphyrins, cytocheratins, phospholipids, and development of spectral fitting analysis of the whole AF signal for their evaluation similarly to an in situ biochemical analysis. The activity is performed by using spectrofluorimetric, microspectrofluorimetric, microscopical and conventional and fluorescence image analysis techniques
