Forensic chemistry is a new
discipline in the Casali Institute. It deals with the use of chemical methods
to resolve crimes and furnish courts of law with scientific evidence. The
main research areas are:
fingerprint visualization Chemical development of latent
fingerprints is expressed by a visual chemical reaction between an
appropriate reagent and one or more constituents of human secretion, to yield
a colored, luminescent, or radioactive product, which can be visualized. The
research concentrates on developing improved reagents and instrumentation for
this purpose, particularly on more sensitive "mapping" of the amino
acids and lipids that are present in small amounts in fingerprint deposits.
The work is done in cooperation with the Latent Fingerprint Laboratory of the
Division of Identification and Forensic Science (DIFS) of the Israel Police.
Advanced techniques for detection and identification of explosives
Cutting-edge techniques for diagnostic determination of explosives are
studied and compared. Another research direction is the preparation of novel
color reagents for the chemical detection of explosives. The work is done in
collaboration with the Explosives Identification Laboratory of the DIFS.
Field tests for crime-scene examination The goal is to
provide forensic technicians with better tools for scientific examination of
scenes of crime. Research problems include: Shooters' detection (color and
fluorescence techniques) and enhancement of faint contact impressions (e.g.
shoe-print, tire-prints, indented writing). The work is done in collaboration
with the Toolmarks and Materials Laboratory and the Questioned Documents
Laboratory of the DIFS.
