Nanoparticles and other subvisible particles potentially present in nearly all trace evidence are often overlooked in forensic investigations. NIJ-supported researchers have characterized several types of particles and developed detection methods.
NIJ-funded research assessing video games designed to reduce sexual assault on campus yielded some positive results, but showed a lack of sustained benefits on key metrics.
Analyzing illicit drugs such as methamphetamine is difficult because the drugs break down when heated in gas chromatographs. Investigators determined that a new method can avoid the heat issue and improve results.
An expert workshop on a hidden hub of crime on the internet identified priority investigative needs, including demystifying the “dark web”, training investigators to identify dark web evidence and activity, and building cross-jurisdictional partnerships.

The technique used to pinpoint mineral deposits, hyperspectral imaging, could be used to find humans, both dead and alive. An NIJ-funded researcher realized that the technology could use drones with sensors to cover large areas and find human bodies.
Identifying individuals through next generation DNA sequencing may involve degraded or mixed samples. A researcher has developed a technique to make fragmented DNA more readable, and a method to help pull individual profiles from mixed samples.
