Abstract
Systems and methods relating thereto for detecting target analytes, using hand-held detection devices and compression mechanisms, are described. An exemplar hand-held detection device includes a cartridge inlet and a cartridge stage for securing cartridge containing the sample including the target-analyte. The device further comprises a compression assembly including a pressing surface. In an open state of the compression assembly, the pressing surface is released, displacing away from the cartridge stage, and thereby allowing a cartridge inlet to provide access to an unobstructed loading path for the cartridge to be secured on the cartridge stage. Upon receiving an external pressing force on the pressing surface, the compression assembly is designed to acquire a compressed state, in which the pressing surface displaces towards the cartridge stage and the compression assembly seals off the cartridge present inside the cartridge stage from an environment around the cartridge stage.
