Abstract: An apparatus includes a flow cell and an image sensor. The flow cell includes a plurality of reaction sites. The flow cell is configured to receive a fluid and an excitation light. Each reaction site is configured to contain a biological sample carried by the fluid. The reaction sites together are positioned along a reaction site plane. The image sensor is positioned to receive light emitted from the reaction site in response to the excitation light. The image sensor defines an imaging surface. The imaging surface defines an imaging surface plane. One or both of the reaction site plane or the imaging surface plane is curved.

Abstract: There is set forth herein, in one example, an apparatus. The apparatus can comprise, for example: a first reaction site and a second reaction site over a single pixel. There is set forth herein, in one example, a method. The method can include, for example: detecting a signal emitted from a first reaction site and a second reaction site; determining the identity of a first analyte of interest in a first reaction site using an amplitude of the detected signal; and determining the identity of a second analyte of interest in a second reaction site using the amplitude of the detected signal.

Abstract: An image sensor structure includes an image layer having an array of light detectors disposed therein. A device stack is disposed over the image layer. An array of light guides is disposed in the device stack. Each light guide is associated with a light detector. An array of nanowells is disposed over the device stack. Each nanowell is associated with a first light guide of the array of light guides. A first primer set is disposed throughout a first well region of each nanowell. A second primer set is disposed throughout a second well region of each nanowell. The second well region is adjacent the first well region. The first and second primer sets are operable to attach a forward strand cluster of forward polynucleotide strands in the first well region and a reverse strand cluster of reverse polynucleotide strands in the second well region.

Abstract: A method of base calling nucleobases of two or more polynucleotide sequence portions, wherein said polynucleotide sequence portions have been selectively processed such that an intensity of the signals obtained based upon the respective first nucleobase is greater than an intensity of the signals obtained based upon the respective second nucleobase.

Abstract: The presently described techniques relate generally to providing motion feedback (e.g., motion system calibration and/or sample alignment) in the context of an imaging system (such as a time delay and integration (TDI) based imaging system). The architecture and techniques discussed may achieve nanoscale control and calibration of a movement feedback system without a high-resolution encoder subsystem or, in the alternative embodiments, with a lower resolution (and correspondingly less expensive) encoder subsystem than might otherwise be employed. By way of example, certain embodiments described herein relate to ascertaining or calibrating linear motion of a sample holder surface using nanoscale features (e.g., sample sites or nanowells or lithographically patterned features) provided on a surface of the sample holder.
