In every forensic investigation, the proper and complete detection and preservation of traces is essential. This applies to both physical and digital evidence. Technological advancements such as portable analytical instruments, hyperspectral imaging, and advanced software make it possible to detect even the smallest traces in a reliable and efficient manner. Challenges include minimizing contamination, maintaining evidential value, and ensuring an uninterrupted chain of custody. Digital evidence such as data from phones, cloud environments or networks requires specific access and validation techniques. Forensic work begins with the trace – and that requires state-of-the-art innovation.
