Portable Kit Can Recover Traces of Chemical Evidence
A chemist at the National Institute of Standards and Technology (NIST) has developed a portable version of his method for recovering trace chemicals such as environmental pollutants and forensic evidence including secret graves and arson fire debris.
Forensics Professor Detects Blood on Revolutionary War Projectiles
More than 230 years after the Revolutionary War ended, Edinboro University professor of forensic science Dr. Ted Yeshion has found the presence of blood on buckshot recovered from a battlefield in upstate New York.
Single Molecule Detection of Contaminants, Explosives or Diseases
A technique that combines the ultrasensitivity of surface-enhanced Raman scattering (SERS) with a slippery surface invented by Penn State researchers will make it feasible to detect single molecules of a number of chemical and biological species from gaseous, liquid or solid samples.
Potential New Tool for Forensic Science
Microbial communities associated with humans tick in predictable, clock-like succession following death.
Perfecting Age Estimations Under 25
The Idaho State University Department of Anthropology has received a $510,409 grant from the National Institute of Justice to develop forensic science techniques to better identify individuals under 25 years of age for criminal justice purposes.
Identifying Gender from a Fingerprint
Culprits beware, a University at Albany research group, led by assistant chemistry professor Jan Halámek, is taking crime scene fingerprint identification to a new level.
Viruses, Too, Are Our Fingerprint
A group of researchers from the University of Helsinki and the University of Edinburgh have been the first to find the genetic material of a human virus from old human bones.
Questioning the Validity of Forensic DNA Match Statistic
Fifteen years of criminal cases with affected mixture evidence.
Study Raises Questions About DNA Evidence
University of Indianapolis researchers say contamination through secondary transfer of material could implicate the innocent or help the guilty go free.
'Forensic Toolkit’ to Improve Evidence Detection and Analysis
Students from The University of Dundee have been developing a forensic `toolkit’ that will allow investigators to determine the age of fingerprints, detect traces of steel on bone from stabbings, and produce a biosensitive spray that can reveal traces of bodily fluids at crime scenes.

New Approach to Determine Time since Deposition of Blood at Crime Scenes
Bookmark and Share

IMPLEN

In a recent study, by the National Center for Forensic Science at the University of Central Florida, a previously unidentified wavelength effect which shows a significant relationship to the lifetime of a blood stain has been discovered. The degree of this wavelength effect allows for more accurate determination of the time since the blood was deposited and it is now possible to differentiate between stains that were deposited minutes, hours, days and months ago. Using the NanoPhotometer™ from Implen the scientists at the National Center for Forensic Science established that tiny bloodstains of only 1 μl could be used for this investigation. One of the benefits of the NanoPhotometer™ is that it is portable and therefore may be taken to the crime scene to first of all confirm that the stain was blood and then to determine how long it had been there. The instrument is perfectly optimized for this forensic application as it may operate from a 12 V DC supply if required, has no moving parts for in-field reliability, does not require regular servicing or calibration and requires very little operator training plus of course it provides high performance on low sample volumes.
