A detection apparatus that includes (a) an array of responsive pads on a substrate surface; (b) an array of pixels, wherein each pixel in the array has a detection zone on the surface that includes a subset of at least two of the pads; and (c) an activation circuit to apply a force at a first and second pad in the subset, wherein the activation circuit is configured to apply a different force at the first pad compared to the second pad, and wherein the activation circuit has a switch to selectively alter the force at the first pad and the second pad.

A device for luminescent imaging includes an array of imaging pixels, a photonic structure over the array of imaging pixels, and an array of features over the photonic structure. A first feature of the array of features is over a first pixel of the array of imaging pixels, and a second feature of the array of features is over the first pixel and spatially displaced from the first feature. A first luminophore is within or over the first feature, and a second luminophore is within or over the second feature. The device includes a radiation source to generate first photons having a first characteristic at a first time, and generate second photons having a second characteristic at a second time. The first pixel selectively receives luminescence emitted by the first and second luminophores responsive to the first photons at the first time and second photons at the second time, respectively.

Apparatus and methods relating to photonic bandgap optical nanostructures are described. Such optical nanostructures may exhibit prohibited photonic bandgaps or allowed photonic bands, and may be used to reject (e.g., block or attenuate) radiation at a first wavelength while allowing transmission of radiation at a second wavelength. Examples of photonic bandgap optical nanostructures includes periodic and quasi-periodic structures, with periodicity or quasi-periodicity in one, two, or three dimensions and structural variations in at least two dimensions. Such photonic bandgap optical nanostructures may be formed in integrated devices that include photodiodes and CMOS circuitry arranged to analyze radiation received by the photodiodes.

A fully integrated miniaturized optical biosensor and methods of making the same are disclosed. The biosensor may include a fluid transport system and an optical system.

Light detection devices and related methods are provided. The devices may comprise a reaction structure for containing a reaction solution with a relatively high or low pH and a plurality of reaction sites that generate light emissions. The devices may comprise a device base comprising a plurality of light sensors, device circuitry coupled to the light sensors, and a plurality of light guides that block excitation light but permit the light emissions to pass to a light sensor. The device base may also include a shield layer extending about each light guide between each light guide and the device circuitry, and a protection layer that is chemically inert with respect to the reaction solution extending about each light guide between each light guide and the shield layer. The protection layer prevents reaction solution that passes through the reaction structure and the light guide from interacting with the device circuitry.

An example apparatus includes a well plate having an array of wells, a light encoding layer positioned under the well plate, an imaging layer to capture an image of the well plate encoded by the light encoding layer, an array of electrodes positioned on a surface of a bottom floor of the at least one well, and a controller. The light encoding layer is to encode light passing through a microscopic object in at least one well of the array of wells. The light encoding layer has a substantially flat form. The controller is to direct electrical voltage to the electrodes to generate a non-rotating, non-uniform electrical field, the electrical field being to rotate an object in the electrical field.

Biosensor including an array of reaction sites and corresponding light sensors may experience crosstalk in which photons from one reaction site are detected by neighbors of its corresponding light sensor, and such crosstalk may be corrected using sharpening kernels corresponding to the sensors in the array. Such sharpening kernels may be derived from generative matrices, which themselves may be derived from point spread functions representing dispersion of illumination emitted from the reaction sites.

A method includes obtaining, from one or more sequencing devices, raw data detected from luminescent labels associated with nucleotides during nucleotide incorporation events; and processing the raw data to perform a comparison of base calls produced by a learning enabled, automatic base calling module of the one or more sequencing devices with actual values associated with the raw data, wherein the base calls identify one or more individual nucleotides from the raw data. Based on the comparison, an update to the learning enabled, automatic base calling module is created using at least some of the obtained raw data, and the update is made available to the one or more sequencing devices.

This invention provides methods and systems for measuring the concentration of multiple nucleic acid sequences in a sample. The nucleic acid sequences in the sample are simultaneously amplified, for example, using polymerase chain reaction (PCR) in the presence of an array of nucleic acid probes. The amount of amplicon corresponding to the multiple nucleic acid sequences can be measured in real-time during or after each cycle using a real-time microarray. The measured amount of amplicon produced can be used to determine the original amount of the nucleic acid sequences in the sample. Also provided herein are biosensor arrays, systems and methods for affinity based assays that are able to simultaneously obtain high quality measurements of the binding characteristics of multiple analytes, and that are able to determine the amounts of those analytes in solution. The invention also provides a fully integrated bioarray for detecting real-time characteristics of affinity based assays.
