A method of detecting the presence of a cathinone moiety in a sample, such as a suspected illicit drug sample, which comprises contacting the sample with a solution comprising neocuproine, a source of copper(II) and a catalyst and observing a colour change, where present, that correlates with the presence of cathinone. The method is operable at environmental temperature. Mechanical elements may be employed to accelerate the colour change if desired.

Cathinone test

A method of detecting the presence of an NBOMe in a sample which comprises of contacting the sample with an activated p-quinone such as 2,3,5,6-tetrachloro-1,4-benzoquinone (TCBQ) and an aldehyde, for example acetaldehyde, and optionally a buffer and observing a colour change, which when present, correlates with the presence of an NBOMe. The ingredients may be provided in the form of a kit which can include a colour standard or comparison chart.

Latent fingerprints on a porous substrate such as paper are developed for viewing and recordal by applying heat to cause the fingerprint to be clearly viewed under radiation to cause the fingerprint to fluorescence (e.g. a few seconds heating with hot air or client contact with a heated device at around 260&#xb0; C.) and viewing under e.g. light of 200 nm to 550 nm with a filter in the yellow to orange wavelength region. Alternatively more extended heating can render the fingerprint assemble under ultraviolet light, and under yet more extended heating permits viewing under white light.
