Fluorometry spectroscopy
WebThe recent application of fluorescence spectroscopy to food analysis is reviewed and future trends in fluorometry are discussed. For food proteins, two techniques, i.e. intrinsic fluorometry and extrinsic fluorometry, are contrasted. Changes in the fluorescence intensity due to tryptophan and the anisotropy were measured in food proteins ... WebEven samples with a single fluorophore can display complex intensity decays due to conformational heterogeneity, resonance energy transfer, and transient effects in diffusive quenching or fluorophore—solvent interactions, to name just the most common origins.
