Abstract: Purifying target biomolecules, such as nucleic acids or proteins, from a biological source is a time intensive process and is typically performed by a skilled technician or scientist owing to the highly technical nature of the work. Systems, devices, and methods disclosed herein enable the automated bioprocessing and purification of target biomolecules from a biological source. For example, an instrument and disposable cartridge are provided for automatedly isolating and purifying nucleic acids (such as plasmid DNA from a bacterial culture) or for isolating protein from any biological sample. Such an exemplary instrument and cartridge can work in concert to timely release, mix, and move the target biomolecule and various reagents and buffers through a target biomolecule purification process, resulting in a purified target biomolecule with less manual oversight than traditional approaches.

Abstract: A method of fabricating a superlattice structure requires that atoms of a first III-V semiconductor compound be introduced into a vacuum chamber such that the atoms are deposited uniformly on a substrate. Atoms of at least one additional III-V compound are also introduced such that the atoms of the two III-V compounds form a repeating superlattice structure of alternating thin layers. Atoms of a surfactant are also introduced into the vacuum chamber while the III-V semiconductor compounds are being introduced, or immediately thereafter, such that the surfactant atoms act to improve the quality of the resulting SL structure. The surfactant is preferably bismuth, and the III-V semiconductor compounds are preferably GaSb along with either InAs or InAsSb; atoms of each material are preferably introduced using molecular beam epitaxy. The resulting superlattice structure is suitably used to form at least a portion of an IR photodetector.
