Abstract: The present disclosure provides methods, device, and system for a hybridization assay to detect nucleic acid targets. The assay may use a probe array format with addressable microwells. Each microwell may retain a plurality of copies of one probe which may be complementary to a portion of a specific nucleic acid target. The plurality of copies of probes may be produced from a pooled library of probe sequences by amplification techniques, including, rolling circle amplification and emulsion-PCR. Detection of hybridization may rely on methods using ion-sensitive field effect transistor (ISFET) and optical detectors to detect signals indicating the presence of the nucleic acid targets.

Abstract: The present disclosure provides methods, device, and system for wafer processing. The wafer processing apparatus uses a nozzle in a lid to disperse a solution to the surface of a wafer. Further, the wafer is positioned on top of a vacuum chuck and does not spin while the solution is dispensed over the surface of the wafer via surface tension, thereby permitting the first solution to react with a reagent on the surface. Further, when dispensing the first solution, a separation gap between the lid and the wafer is at a predetermined distance, for example, from about 20 ?m to about 2 mm.

Abstract: The present disclosure provides methods and apparatus for reducing bubble formation during incubation processes. The incubation process, e.g., a hybridization process for a hybridization solution, can be more than a few hours, during which there are bubbles formed at the end of the incubation process. The present disclosure provides a hybridization method with reduced bubble formation at the end of the hybridization process.

Abstract: The present disclosure relates to processes for inverting oligonucleotide probes in an in situ synthesized array. These processes can be used to reverse the orientation of probes with respect to the substrate from 3?-bound to a substrate to 5?-bound to another substrate. These processes can also be used to reduce or eliminate the presence of truncated probe sequences from an in situ synthesized array. These processes can preserve the original patterns of the synthesized oligonucleotide after the inversion. These process can be achieved via the formation of a hydrogel layer in-between a donor substrate and an acceptor substrate through a polymerization reaction forming the hydrogel layer.

Abstract: The present disclosure provides methods and processes for forming a pattern of oligonucleotides on a microarray. A method for forming a pattern of oligonucleotides on a microarray may include forming a photoresist layer by applying a photoresist composition onto an underlying layer of a substrate, exposing a dose of light through a patterned mask onto the substrate, and removing protective groups on a section of the plurality of functional groups within at least one exposed region of the substrate, wherein the photoresist composition comprises a photoacid generator, an acid scavenger and a photosensitizer, wherein the underlying layer comprises a plurality of functional groups protected by protective groups; thereby forming a pattern on the substrate, wherein the pattern comprises the at least one exposed region, and wherein the at least one exposed region is no more than 1 micrometer in at least one dimension.
