Making Use of What’s Not Visible in Trace Evidence Examinations

Date Published

July 6, 2020

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.
