A system includes: an objective lens; a first light source to feed first illuminating light through the objective lens and into a flowcell (e.g., with a relatively thin film waveguide) to be installed in the system, the first illuminating light to be fed using a first grating on the flowcell; and a first image sensor to capture imaging light using the objective lens, wherein the first grating is positioned outside a field of view of the first image sensor. Dual-surface imaging can be performed. Flowcells with multiple swaths bounded by gratings can be used. An auto-alignment process can be performed.

Illumination for fluorescence imaging using objective lens

In an example of the method, a functionalized coating layer is applied in depressions of a patterned flow cell substrate. The depressions are separated by interstitial regions. A primer is grafted to the functionalized coating layer to form a grafted functionalized coating layer in the depressions. A hydrogel is applied on at least the grafted functionalized coating layer.

Fiducial markers are provided on patterned arrays of the type that may be used for molecular analysis, such as sequencing. The fiducials may have configurations that enhance their detection in image or detection data, that facilitate or improve processing, that provide encoding of useful information, and so forth. Examples of the fiducials may include an 'always on' type that respond to multiple frequencies of radiation used during processing and detection so as to return signals during successive cycles of imaging.

System and method with fiducials responding to multiple excitation frequencies

Fiducial markers are provided on patterned arrays of the type that may be used for molecular analysis, such as sequencing. The fiducials may have configurations and layouts that enhance their detection in image or detection data, that facilitate or improve processing, that provide encoding of useful information, and so forth. Examples of the fiducials may include offset layouts that may be useful in detecting the fiducials in different types and approaches in imaging, and that may help to distinguish regions of the array from one another in image data.

System and method with fiducials having offset layouts

A scanning apparatus that can include (a) a scan actuator including a linear actuator and a mount for a removeable vessel, wherein the mount has a mechanical fastener that is configured to engage a complementary mechanical fastener on the removeable vessel, and wherein the linear actuator is configured to translate the mount while the mechanical fastener engages the complementary mechanical fastener on the removeable vessel; (b) a reference surface; and (c) a preload configured to urge the vessel to contact the reference surface, wherein the linear actuator is configured to slide the vessel along the reference surface while the preload urges the vessel to contact the reference surface.

Scanning apparatus and methods for detecting chemical and biological analytes

Fiducial markers are provided on patterned arrays of the type that may be used for molecular analysis, such as sequencing. The fiducials may have configurations that enhance their detection in image or detection data, that facilitate or improve processing, that provide encoding of useful information, and so forth. Examples of the fiducials may include a non-closed shape that may encode information, allow for bubbles to escape during manufacture, and provide additional advantages over closed shape fiducials.

Fiducial markers are provided on patterned arrays of the type that may be used for molecular analysis, such as sequencing. The fiducial markers may have configurations that enhance their detection in image or detection data, that facilitate or improve processing, that provide encoding of useful information, and so forth. Examples of the fiducial markers may include features and materials that are provided on or in the support of a patterned array and that return at least a portion of incident light by reflection. The fiducial markers may form gratings or other encoding configurations that assist in image processing, alignment, or other aspects of processing of the patterned array.

System and method with reflective fiducials for locating or registering locations receiving biological samples in successive cycles of fluorescent imaging

Fiducial markers are provided on a patterned array of the type that may be used for molecular analysis, such as sequencing. The fiducial markers may have configurations and layouts that enhance their detection in image or detection data, that facilitate or improve processing, that provide encoding of useful information, and so forth. Examples of the fiducial markers may include non-rectilinear layouts that may provide for more robust location of both the fiducial markers and sites of the patterned array.

System and method with fiducials in non-rectilinear layouts

An apparatus can include a vessel, a reference surface, a preload, a scan actuator, and a transmitter. The reference surface can form a structural loop with a detector. The preload can be configured to urge the vessel to contact an area on the reference surface. The scan actuator can be configured to slide the vessel along the reference surface in a scan dimension. The transmitter can be configured to direct signal from the vessel to a detector and/or direct energy from an energy source to the vessel, when the vessel is urged by the preload to contact the reference surface.
