Abstract
An example of a flow cell includes a substrate and a cationic polymeric hydrogel on the substrate. The cationic polymeric hydrogel includes a cationic moiety that is i) integrated into a monomeric unit of an initial polymeric hydrogel or ii) attached to the monomeric unit of the initial polymeric hydrogel through a linker. The flow cell further includes an amplification primer attached to the cationic polymeric hydrogel.
