Performances on old blood

Not only BLUESTAR® FORENSIC can help investigators to solve crimes weeks or months after it was perpetrated, it can also take us back to the past decades or even centuries and give us additional clues to historical events. A great tool for archaeology.

Evaluation of the opportunity of using Bluestar in archeology by Barbara J. Gundy, Ph.D. This study is about searching for blood on lithic artifacts.


7,000-year-old camelid blood found by BLUESTAR on argentinian lithic artifacts

7,040 years old ! So far, this is the oldest blood revealed by BLUESTAR® FORENSIC. This awesome discovery was made by Argentinian archeologist Andrés Romano of ISES-CONICET-UNT by spraying Bluestar Magnum on archaeological lithic material and the images are eloquent... The projectile tip of PCz 1.2 (Peñas de la Cruz, Argentina) is dated 7,040 ± 90 years before present and those of Quebrada Seca (QS3) around 6,000 years BP. The reaction in these old samples could be clearly observed from the photographs. A scanning electron microscope (SEM) was later used to look for blood cells of camelids in the areas where bluestar reacted.

The blood of two confederate soldiers revealed at Gettysburg

BLUESTAR® FORENSIC revealed blood prints of two confederate soldiers that were killed at the Battle of Gettysburg. This decisive battle of the American Civil War was fought in July 1863, more than 145 years before the reagent was applied !
