In one example, a method of preparing a fluidic channel includes covalently coupling a first region of a substrate to a first region of a cover using first moieties covalently coupled to the first region of the substrate and second moieties covalently coupled to the first region of the cover. The covalent coupling between the first region of the substrate and the first region of the cover suspends a second region of the cover over a second region of the substrate to form a fluidic channel.

A method for patterning flow cell substrates using photo-initiated chemical reactions that includes fabricating a planar waveguide flow cell by forming a layer of light coupling gratings on a glass substrate layer; depositing a core layer on the layer of light coupling gratings; depositing a cladding layer on the core layer; and forming nanowells in the cladding layer; silanizing the cladding layer; coating the silanized cladding layer and nanowells with a first group of reactants; introducing a second group of reactants into the nanowells, wherein the second group of reactants includes a target reactant and a light-sensitive photoinitiator system; coupling a light source to the light coupling gratings and directing light internally within the planar waveguide flow cell for photo-initiating a chemical reaction between the first and second groups of reactants, wherein the photo-initiated chemical reaction covalently binds the target reactant to only the bottom portion of each nanowell.

System and method for patterning flow cell substrates

An interposer for a flow cell comprises a base layer having a first surface and a second surface opposite the first surface. The base layer comprises black polyethylene terephthalate (PET). A first adhesive layer is disposed on the first surface of the base layer. The first adhesive layer comprises methyl acrylic adhesive. A second adhesive layer is disposed on the second surface of the base layer. The second adhesive layer comprises methyl acrylic adhesive. A plurality of microfluidic channels extends through each of the base layer, the first adhesive layer, and the second adhesive layer.

Presented are methods and compositions for spatial detection and analysis of nucleic acids in a tissue sample. The methods can enable the characterization of transcriptomes and/or genomic variations in tissues while preserving spatial information about the tissue.

Spatial mapping of nucleic acid sequence information

A plurality of isolated microvessels including a plurality of encoded microvessels each having a microbody and a reservoir core. The microbody is configured to separate a biological or chemical substance in the reservoir core from an ambient environment surrounding the microbody. The microbody includes a transparent material that at least partially surrounds the reservoir core and facilitates detection of an optical characteristic of the substance within the reservoir core. The microbody of each microvessel includes an identifiable code that distinguishes individual microvessels of the plurality of encoded microvessels from each other. The plurality of isolated microvessels also includes a plurality of compartments each configured to separate individual microvessels of the plurality of encoded microvessels from each other.

Microvessels, microparticles, and methods of manufacturing and using the same

A method of reading a plurality of encoded microvessels used in an assay for biological or chemical analysis. The method can include providing a plurality of encoded microvessels. The microvessels can include a respective microbody and a reservoir core configured to hold a substance in the reservoir core. The microbody can include a material that surrounds the reservoir core and facilitates detection of a characteristic of the substance within the reservoir core. Optionally, the material can be transparent so as to facilitate detection of an optical characteristic of a substance within the reservoir core. The microbody can include an identifiable code associated with the substance. The method can also include determining the corresponding codes of the microvessels.
