Abstract
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.
