Abstract
•Micronised Egyptian blue pigment used as safe, simple treatment to visualise latent fingerprints.•Treated fingerprints visualised using intense near infrared luminescence of pigment.•Allows detection of latent fingerprints on highly patterned and reflective surfaces.
In this paper we demonstrate that micronised Egyptian blue pigment can be used as a safe and simple material to visualise latent fingerprints on non-porous surfaces as near-infrared luminescent impressions. This allows the detection of latent fingerprints on highly patterned and reflective surfaces that have proven challenging with existing techniques.
