New forensic method can catch armed criminals green-handed

Teams at AMOLF and University of Amsterdam developed a new method detecting gunshot residue using perovskite photoluminescence.
When a firearm discharges, lead residue deposits on surfaces, and current methods are lab-dependent.
The method converts lead particles into light-emitting semiconductors, revealing green patterns even after washing or two meters away.
Bente van Kralingen states detecting residue is a major advantage for answering key questions.
This forensic leap aids incident reconstruction, but a positive result requires careful interpretation.

Science at the service of human rights

All bodies leave traces. But it is not always easy to follow these traces and reconstruct their course based on the remains. Science can help in this task: forensic anthropology in particular, but history, archaeology, medicine, physics, chemistry and other fields of science are also useful for this. To conclude the International Conference on Culture and Peace, organized on the occasion of the 88th anniversary of the bombing of Gernika, a round…
