Effective Long-Term Preservation of Biological Evidence

The goal of this project is to identify the optimum method to preserve DNA associated with forensic evidence using commercial off-the-shelf chemical preservatives (e.g. antimicrobial agents, chelators/fixatives, and nuclease inhibitors). Researchers propose to conduct this study in 1 year, divided into two phases. Phase I will consist of a real-time and accelerated aging study that tests nine chemical preservatives individually. During phase II and after the accelerated aging results of phase I are evaluated, the preservatives with the most promising results will be combined to examine whether this will enhance the effects.
