A sample capture and transport unit comprises a housing defining a substrate chamber for containing a sample-capture substrate. The housing comprises at least a first part and a second part which are movable relative to one another &#x22c5; i) from a first closed configuration in which the substrate chamber is inaccessible; &#x22c5; ii) to a first open configuration in which access to the substrate chamber is enabled to allow capturing of a skin-print on a sample-capture substrate contained within the substrate chamber; and subsequently &#x22c5; iii) into a second closed configuration in which the substrate chamber is again inaccessible. The unit further comprises a retaining mechanism for retaining it in the second closed configuration. The retaining mechanism is disablable to permit movement of the unit out of the second closed configuration. A sample can be obtained at a first location, secured for transport and analysed at a second location.

Sample capture and transport unit

A method of analyzing a skin-print provided on a first surface of an optically transparent substrate. The method comprises the steps of exposing the skin-print on the first surface of the optically transparent substrate 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 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 a skin-print analysis apparatus and a reagent cartridge for use in carrying out the method.
