A hydrogel includes a dendritic core with 2 to 30 arms, and first and second acrylamide monomers incorporated into each arm. The first acrylamide monomer is: (I), wherein Rand Rare independently selected from an alkyl, an alkylamino, an alkylamido, an alkylthio, an aryl, a glycol, and optionally substituted variants thereof; and the second acrylamide monomer is: (II), wherein Rand Rare independently hydrogen or an alkyl; L is a linker including a linear chain of 2 to 20 atoms selected from carbon, oxygen, and nitrogen and optional substituents on the carbon and any nitrogen atoms; A is an N substituted amide: (III), where Ris hydrogen or an alkyl; E is a linear chain of 1 to 4 atom(s) selected from carbon, oxygen and nitrogen, and optional substituents on the carbon and any nitrogen atoms; and Z is an optional nitrogen containing heterocycle.

Hydrogel

An example of a functionalized plasmonic nanostructure includes a plasmonic nanostructure core; a polymeric hydrogel attached to the plasmonic nanostructure core, the polymeric hydrogel having a thickness ranging from about 10 nm to about 200 nm; and a plurality of primers attached to side chains or arms of the polymeric hydrogel, wherein at least some of the plurality of primers are attached to the polymeric hydrogel at different distances from the plasmonic nanostructure core.

Functionalized plasmonic nanostructures

In an example, a flow cell includes a substrate, a selectively removable porous molecular network on the substrate and defining exposed substrate regions, and sequencing surface chemistry on at least some of the exposed regions. The sequencing surface chemistry is selected from the group consisting of i) an activated pad, a polymer layer attached to the activated pad, and a primer attached to the polymer layer; or ii) a nanostructure and an enzyme attached to the nanostructure.

Flow cells

An example of a method includes providing a substrate with an exposed surface comprising a first chemical group, wherein the providing optionally comprises modifying the exposed surface of the substrate to incorporate the first chemical group; reacting the first chemical group with a first reactive group of a functionalized polymer molecule to form a functionalized polymer coating layer covalently bound to the exposed surface of the substrate; grafting a primer to the functionalized polymer coating layer by reacting the primer with a second reactive group of the functionalized polymer coating layer; and forming a water-soluble protective coating on the primer and the functionalized polymer coating layer. Examples of flow cells incorporating examples of the water-soluble protective coating are also disclosed herein.

Protective surface coatings for flow cells
