This research project I made in 2011 – 2012.
In this article are exceptional results with Acid Yellow 7 and Hungarian Red, after treatment with Luminol and LCV.
The title of this article:
New Insight into the Chemical Improvement of Shoeprints and Fingerprints Placed with Blood on Non-Porous Surfaces
Abstract:
Shoe prints and finger prints placed in blood on non-porous substrates are usually treated with chemical means to achieve a better contrast of the blood traces on the carrier material. The subject of this research was to explore the possibilities to improve visualization of blood traces, after they were detected with Luminol, by exposing them to other chemicals, such as LCV, Acid-Yello-7 and/or Hungarian Red.
This research led to some very interesting results, which show that LCV appears to be an less suitable chemical to improve this visibility on non-porous substrates.
