Abstract
The invention relates to a method and apparatus for imaging and documenting fingerprints. A fluorescent dye brought in intimate proximity with the lipid residues of a latent fingerprint is caused to fluoresce on exposure to light energy. The resulting fluorescing image may be recorded photographically.
Claims12
A method of imaging a latent pattern of lipid residues comprising the steps of:
- contacting the residues with a dye having an affinity for lipids, wherein said dye fluoresces when in proximity to the lipids and excited by an appropriate energy source;
- exposing said dye to an energy source for exciting said dye to fluoresce;
- and
- observing the fluorescing image formed thereby;
- wherein said dye is one or more members of the dyes of the styryl family consisting of:
2 more elements
A method of imaging a latent fingerprint comprising the steps of:
- contacting the latent fingerprint with a dye having an affinity for lipid residues which comprise the fingerprint, which dye fluoresces when in proximity of the lipid residues and excited by an appropriate energy source;
- exposing the dye to an energy source to cause fluorescing excitation;
- and
- observing the fluorescing fingerprint image formed thereby;
- wherein said dye is one or more members of the dyes of the styryl family consisting of:
2 more elements
