DATING BLOODSTAINS AND BIOLOGICAL FLUIDS WITH FLUORESCENCE LIFETIME TECHNIQUES

摘要

Methods of aging biological samples through the use of fluorescence lifetime are disclosed herein. These methods provide aging of samples such as bloodstains using endogenous fluorophores and conformational protein changes. Advantageously, the methods provide the average fluorescence lifetime across a region of interest in a biological sample, thereby minimizing problems with sampling and providing accurate results.
