Abstract
A method of detecting the presence of fentanyl or a fentanyl analogue in a sample which comprises contacting the sample with a 1,2 naphthoquinone (such as 1,2-naphthoquinone itself) in a solvent, preferably acetonitrile, and observing a colour change, which when present, correlates with the presence of fentanyl or a fentanyl analogue. Optionally, a buffer may be provided to maintain an alkaline environment and/or a metal halide catalyst and/or light source may be added to accelerate colour development.
