Lanthanide complexes are employed in photoluminescence detection of fingerprints because their long luminescence lifetimes allow use of time-resolved imaging techniques to suppress problematic background fluorescence. To date, however, these complexes have been unsuccessful when used in developing old fingerprints on porous substrates. SYPRO®Rose Plus Protein Blot Stain remedies this shortcoming; it lends itself to smooth surfaces as well, thus having potential as a universal fingerprint reagent.

The extension of fluorescence measurements of samples from steady state to dynamic methods offers the possibility to extract valuable information at the micro and nano level. Imaging of fluorescent samples with nanosecond resolution often imposes challenging problems, especially when dealing with very weak optical and electrical signals. In this context, this paper discusses the detection of latent fingerprint samples with nanosecond resolution. Imaging of fingerprint samples, which are deposited on strongly fluorescing substrates, is carried out by the subsequent suppression of the unwanted background fluorescence emissions using the time-resolved optical technique. "signature" characterisation of fingerprint samples treated with fluorescent magnetic powders is also carried out.
