Abstract: 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 ? i) from a first closed configuration in which the substrate chamber is inaccessible; ? 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 ? 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.
