Stokes shift emission spectroscopy of human tissue and key biomolecules

The Stokes-shifted emission spectra were measured for various photoactive biomolecules in aqueous solution and tissue such as tryptophan, collagen, nicotinamide adenine dinucleotide, and flavin. Information is obtained on the molecular activity in the tissue. This new approach allows for the extract...

Zusammenfassung:The Stokes-shifted emission spectra were measured for various photoactive biomolecules in aqueous solution and tissue such as tryptophan, collagen, nicotinamide adenine dinucleotide, and flavin. Information is obtained on the molecular activity in the tissue. This new approach allows for the extraction of some new information not obtained from excitation and/or fluorescence spectroscopy for a single spectral scan.
