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.

Systems and methods using hand-held devices for detecting a target analyte loaded on a cartridge

A cartridge for providing a target analyte for detection is described. One such exemplar cartridge includes a base portion including: (1) a receiving area disposed at or near a center region of the base portion; (2) multiple reaction wells disposed outside the center region or radially disposed at or near a perimeter of the base portion; and (3) multiple connecting tracks that substantially linearly extend from a region at or proximate to the receiving area to the multiple reaction wells and designed to convey a sample including the target analyte from the receiving area to the multiple reaction wells, each of which are configured to transform the sample to a detectable sample. Systems and methods of reacting and detecting the sample including the target analyte are also described.

Systems and methods for determining presence and/or characteristics of target analytes in a sample

Aniosotropic Ratchet Conveyor ('ARC')-based biomolecule processing devices and related methods are described. The ARC-based biomolecule processing devices include (i) a substrate having an ARC track defined on or within the substrate and including a biomolecule receiving area, which is designed to receive biomolecule, and a reconstituting area, which is designed to contain dry reagents and is designed to receive a transport solution such that at the reconstituting area, dry reagents are reconstituted with transport solution; and (ii) a microheater area disposed at or near the biomolecule receiving area, fitted with a microheater, which is designed to heat biomolecule that is received through the biomolecule receiving area and designed to process heated biomolecule and dry reagents reconstituted with transport solution. The ARC track includes an arrangement of a plurality of hydrophilic rungs disposed on a hydrophobic region such that between consecutive hydrophobic rungs, a portion of the hydrophobic region is exposed.
