What's In a Fingerprint?

A person’s fingerprint includes traces of chemicals which, when tested, can reveal the substances a person has eaten, injected or inhaled.


When a person inhales smoke, the chemicals are absorbed and processed by the body, producing secondary chemicals called metabolites. Metabolites can be detected within a person’s sweat for many hours, sometimes even days, later.
If someone has smoked or taken any other drugs, analysis of that person’s sweat – even the tiny amount in their fingerprints – can provide evidence of this activity long afterwards.



Proprietary Drug Screening Reagents

Intelligent Fingerprinting’s scientists have developed highly sensitive reagents for the detection of trace substances in fingerprint sweat. The reagents use patented technology based on antibody nanoparticle conjugates to detect specified substances such as drug metabolites. Our proprietary reagents can be formulated to screen for more drugs than the five groups currently available. Such flexibility allows our drug testing system to adapt to changing drug abuse patterns, as well as the requirements of different drug screening customers.

Pioneering Research

Intelligent Fingerprinting’s drug screening technique is based on the pioneering nanoparticle technology research of our Founder and Chief Scientific Officer, Professor David Russell of the University of East Anglia.

Professor Russell’s research, which has been published in leading scientific journals, focuses on the study of metabolites and their detection within sweat. Through his work he discovered that drug abuse could be detected through fingerprint analysis.

Future Applications

Intelligent Fingerprinting’s non-invasive diagnostic technique may be used to identify other types of metabolites and chemicals found in fingerprint sweat. Research of new uses for this technology is ongoing.
