One of the crucial tasks of a crime scene investigation is the search for latent fingerprints. The most common technique for the detection and development of latent fingerprints is the use of brushes with carbon black powder. As DNA analysis of latent fingerprints is already a common technique to obtain additional information, 51 used latent fingerprint brushes were analyzed to check if the brushes may be a source of DNA contamination. On 86% of the tested brushes, DNA could be observed in partial or full profiles, mostly as DNA mixtures. Following these pre-testing results, a secondary transfer study was carried out with used and artificially contaminated brushes. The typing results of these tests could prove a limited DNA contamination risk via latent fingerprint brushes via secondary transfer.

Quickly and easily dust for fingerprints in the lab or field crime scene. This disposable latent print brush features the same ultra-soft fiberglass filaments that have been used for decades in Zephyr® fingerprint brushes. Each brush is individually packed and sealed, so there are no contaminates that could be deposited at the crime scene. Available to U.S. customers only.
