1. Researchers at Nelson Mandela University have developed a novel carbon composite powder for enhancing fingerprint imaging, capturing nanoscale features more vividly. 2. The powder, made from manganese-doped iron oxide nanoparticles coated with activated wool char, improves contrast and is safer to use than traditional methods. 3. The team used a hydrothermal method to create the nanoparticles, which showed promising results in imaging tests, potentially expanding applications in forensic investigations.
