What is fingerprinting?
This test, introduced in the 1920s by Karl Landsteiner, identifies the unique proteins present in human blood.
What is blood typing?
This portable paper-based microscope can magnify objects up to 140 times and is often used in science education and field research.
What is a Foldscope
This forensic technique, developed in the late 19th century, allows investigators to match bullets and shell casings to specific firearms.
What is ballistics analysis?
This field, essential for analyzing microscopic traces of drugs and toxins in body fluids, has been extensively developed through the contributions of experts like Richard Saferstein.
What is toxicology?
This type of software is used to digitally reconstruct events, providing investigators with a 3D visualization of what happened at a crime scene.
What is crime scene recreation software?
This type of evidence has revolutionized the field of criminal justice by allowing investigators to identify suspects, exonerate the innocent, and solve cold cases with unparalleled accuracy, thanks to biological material left at crime scenes.
