文摘
- •
Fingermark autofluorescence changes with time, both spectrally and in intensity.
- •
Aging products are identified using thin layer chromatography and spectroscopy.
- •
Main contributors to the autofluorescence of aged marks are tryptophan derivatives.
- •
Indoleacetic acid, (nor)harman and xanthurenic acid are indicated key contributors.
