Absorption, fluorescence, and fluorescence excitation spectra of thioflavin T in aqueous solutions and polyvinyl alcohol films were studied. The dye aggregated when its concentration was increased. This was accompanied by a hypsochromic shift of the absorption spectrum and a bathochromic shift of the fluorescence spectrum. It was shown that fluorescence of the probe embedded in amyloid fibrils was caused by monomers rather than dimers or other aggregates.
