MD.20.011 – CrimeSceneDx: development of a realtime detection & analyzing device for crime scene research by using lab-on-chip technology.

Route: Measuring and detecting: anything, anytime, anywhere

Cluster question: 058 What are the patterns and causes of crime and how can we influence them?

When a detective officer arrives at a crime scene, an enormous challenge awaits. In all chaos and hectics, characteristic for crime scene research, important decisions have to be taken. Crucial questions like ‘What happened?’, ‘In what way?’, and ‘Who is responsible?’ need to be answered quickly. This is easier said than done. Trace-carriers are gathered which may shed more light on the situation after analysis in a forensic laboratory. This analysis however, but also the search for and securing of relevant trace carriers is a tricky and time consuming job. Time is valuable often one does not know what the trace found is and whether it is relevant or not. To get answers faster it is important for crime scene research to have an indicative test. A cheap, simple and reliable instrument -comparable with the well-known pregnancy test- supplying one in the field an immediate indication. This kind of devices do not exist for crimescene research, but this need can be answered by using lab-on-a-chip technologies. This would place the forensic lab right on the spot. The analyses normally done in a laboratory can be integrated in a chip in the size of a few centimeters. The new tool can determine what biological traces are (blood, sperm, urine, etc.), if there is DNA in the sample and what is the amount of possible donors. Besides that also chemical traces can be analyzed at the scene to get an indication of what it is (narcotics, explosives, chemical residues, etc.). Through a design taking care of building up evidence and possible contra research, a device can be developed to be used during the entire detection process.
