摘要：
A method of analysing a skin-print provided on a first surface of an optically transparent substrate 200. The method comprises the steps of exposing the skin-print on the first surface of the optically transparent substrate 200 to one or more reagents selected to bind with one or more metabolites present in the skin-print； transmitting electromagnetic radiation onto the skin-print through the optically transparent substrate using a radiation source 140 to thereby produce an optical signal of said one or more reagents and/or said one or more metabolites； and detecting an optical image of the optical signal through the optically transparent substrate using a sensor. Also included is a reagent cartridge 300, the body of which has an open topped recess in the surface and a plurality of reservoirs 312, 313 each associated with a dispensing port 319. Further included in the cartridge is an actuator to dispense the fluid from the reservoirs through the associated dispensing ports. In use a test substrate seals the recess and dispensing port.
