An example of a kit includes a flow cell, a primer fluid, and a cleaving fluid. The flow cell includes at least one surface functionalized with a polymeric hydrogel including azide functional groups or amine functional groups. The primer fluid includes a plurality of alkyne-containing primers, each alkyne-containing primer having an amino cleavable group attaching a primer sequence of the alkyne-containing primer to an alkyne-containing moiety of the alkyne-containing primer. The cleaving fluid includes a substance that is reactive with the amino cleavable group.

Disclosed herein are methods of making active, food-grade packaging resins using a reactive extrusion step that involves reacting a polymeric material with a ligand and one of a cross-linking agent and a radical initiator in an extruder, under temperature and pressure conditions effective to cause covalent binding of the ligand to the polymeric material by a linker that is the reaction product of the cross-linking agent or by direct bond formation between the ligand and the polymeric material, and then extruding the active, food-grade packaging resin. Also disclosed are the active packaging resins obtained from such methods, methods of forming food packaging materials from the active packaging resins, the food packaging materials that contain the active packaging resins, and methods of packaging perishable food in those food packaging materials.
