Rodney Shenck wanted me to be sure to mention the University of Southern Mississippi's Third Annual "Forensic Science Seminar At Sea", August 6-13, 2006.  The seminar takes place aboard the Carnival Cruise Lines departing from Galveston, Texas with stops in Montego Bay, Jamaica, Grand Cayman, & Cozumel, Mexico.  Instructors include Dr. Henry Lee, Ron Smith, Rodney Schenck, John Byrd, Dr. Robert Barsley, Dr. Mary E. Case, Karen Chabert, Gary Hargrove, Deborah St. Germaine, and Dr. Doug Ubelaker.  Rates range from $1,170 to $1,495 depending on participation and room selection.  For more details, visit the link below:


Last week

we looked at a recent study on the accuracy of latent print examination.

This week

we look at several references on the use of nanoparticles for latent print development, an area that offers promise in our discipline.


Nanoparticles clearly finger the culprit

Oil-seeking nanoparticles could give police the clearest fingerprints yet, suggests new research.

Law enforcement officers currently search for prints by dusting a crime scene with fluorescent powder. This sticks to the oily residue left by the fingertip, showing up the whorls and ridges. But sometimes the prints are not clear enough to finger a suspect.

The new dust made of sticky nanoparticles could help. The powders used today work because oily prints have a natural tackiness. But the nanoparticle dust being developed at the University of Sunderland in the UK will actively seek out any oil.

The nanoparticles are tiny glass spheres between 200 and 600 nanometres in diameter. As well as being speckled with a fluorescent dye, they are coated with hydrophobic molecules, which are repelled by water and attracted to oil. So they fix tightly to the fingerprint.

Fred Rowell, who is leading the research, says the nanoparticles should pick out even the faintest of fingerprints because they stick to tiny traces of oil. And the prints should be much sharper, providing fine detail that can be crucial to identifying a print, such as how ridges in the print branch and finish.

While the research is in its early stages, Rowell hopes he piqued the interest of the police by presenting the project at the Nanotechnology in Crime Prevention and Detection conference held in London last week.

Glowing Fingerprints Plan Backed

Forensic experts hope proposals for a new research project will lead to the first major breakthrough in fingerprint technology for over 20 years.

The research will involve the use of microscopic (nano) particles which can bind to fingerprints to make them glow.

Northamptonshire Police Scientific Support Unit and scientists at St Andrew's University in Fife, Scotland will carry out the research.

The project is expected to last two years and could cost about 250,000.

Head of Northamptonshire Police Scientific Support Dr John Bond said: "If we are successful it will have a tremendous impact on enhancing fingerprints and hence increase fingerprint detections and will be the first major step forward in fingerprint technology since the 1980s.

"Amongst other things it will help solve the problems of seeing fingerprints on surfaces where the contrast against background is poor and also on surfaces that have become wet.

"The end result will mean that police find more fingerprints and detect more crime."

The research project has been approved but funding is now being sought from industry, the Forensic Science Service and the Home Office.

Roland E. Menzel's ongoing work before he recently passed away was:
"the universal application of lanthanide complexes and photoluminescent semiconductor nanoparticles to latent fingerprint detection in concert with time-resolved imaging for background fluorescence suppression."
