Abstract:
Systems and methods for multiple analyte detection include a system for distribution of a biological sample that includes a substrate, wherein the substrate includes a plurality of sample chambers, a sample introduction channel for each sample chamber, and a venting channel for each sample chamber. The system may further include a preloaded reagent contained in each sample chamber and configured for nucleic acid analysis of a biological sample that enters the substrate and a sealing instrument configured to be placed in contact with the substrate to seal each sample chamber so as to substantially prevent sample contained in each sample chamber from flowing out of each sample chamber. The substrate can be constructed of detection-compatible and assay-compatible materials.

Abstract:
The present application relates to embodiments of fluidic devices having a pressure-balancing fluidic network designed for positioning an aliquot of liquid in the fluidic network. In various embodiments of a pressure-balancing fluidic device, a fluidic network may be designed so that filing the fluidic network includes loading an aliquot of a fluid through an inlet under an applied pressure, and positioning the aliquot of fluid in the fluidic network using the equalizing forces of the gas pressure in a pressure-compensating portion of the fluidic network and the fluid pressure at the inlet.

Abstract:
A fluid processing method, adapted to produce different oligomers in a plurality of respective reaction sites is claimed. The described fluid processing device comprises a first manifold for delivering reactants to the plurality of reaction sites, a second manifold for removing waste from and, optionally, delivering wash fluid to the plurality of reaction sites. Surface tension controlled valves can be disposed in fluid communication with the first manifold, the second manifold or both. They can selectively allow reactants and/or fluids into the reaction sites. The valves can be configured by light activation, e.g. by directing electromagnetic radiation towards them whereby reflecting of the radiation can be controlled by a plurality of mirrors. Electrowetting, optoelectrowetting, thermo capillary effects represent examples of triggering liquid movement. A method of synthesizing oligonucleotides is also disclosed.
