Uh oh...

by blogger team UAB DB

Uh oh...undetectable blood? Not good for forensic examiners. And why do we continue to help out criminals through the media. If these detergents with active oxygen do work new methods of detection will have to be developed.

"Regardless of the type of material used and the time that had elapsed, in every single case where the three tests were performed, the presence of blood was not detected...".

Common blood enhancers such as phenophthalene and luminol were used in the study and gave negative results for blood on every cloth washed with the active oxygen detergents. I wonder if IR photography could work to show the presence of blood after washing? I'm sure someone's alreeady on that though, at least I hope so.

Hey, do you have any sources for this? I'm looking for master thesis ideas and I'm interested in this one.
