Innovative technology for production of more accurate and versatile fingerprint dust.

The fingerprint challengeMan sweeping for fingerprints

Identification of an individual's fingerprint can be crucial in circumstances such as establishing a person's identity and remains an essential process for investigation and prevention of crime. The most efficient, simple and cost-effective way to detect and track sweat-fatty traces is processing them with magnetic dactyloscopy powders. Such powders are limited to defining ridge patterns and do not always fully reveal the imprint. Thus reliability and validity are both major issues when attempting to recover fingerprint traces. Currently different colour powders are used for different surfaces as one colour can not provide enough contrast and clarity given the diversity of different fluorescent backgrounds.

The market

Currently the global market for forensic powders and chemicals  is worth $800m. The fingerprint powders market itself is more than $90m and growing.

Nano-sized magnetic powder

Researchers from the Tomsk Polytechnic University in Russia have developed a ground-breaking technology for the production of nano-sized iron (magnetic) particles using the method of electric explosion of conductors (EEC), a novel and efficient manufacturing process. Some of the many benefits of their nano powder in comparison with current fingerprint powder products include:

  • Improved resolution and higher reliability
  • Improved imprints obtained on most common surfaces such as glass, polymer bags and glossy paper (for drugs trafficking)
  • Removal of prints from a greater number of materials, including polyethylene and glossy paper, traditionally considered to be difficult materials from which to recover fingerprints.
  • Versatile product which means one kit of powder is sufficient to detect fingerprints in different backgrounds and surfaces.
  • Cost-effective manufacturing process compared to traditional methods

About the team

A team of researchers from Tomsk Polytechnic University with experience in studying and experimenting the structures and properties of nanometals.

The technology was developed in 2010, after which production of powder started in 2011. The powder has so far been supplied to several forensic departments in Moscow and Tomsk and expert opinion was obtained. The Criminal Expertise Department in Tomsk has issued a certificate to acknowledge the efficacy and visible improvement of the nano powder results compared to existing fingerprint detection powders.

Patent status

First patents (Russia) were obtained in 2012. The plan is to file for patents internationally. No prior novelty has been found so far.

The researchers are interested in raising investment for scaling the production in Tomsk and selling the product in Russia and abroad. Contact the Isis Enterprise Consultant by clicking on the link below.
