Abstract
Disclosed herein is a material comprising a functionalized solid support surface, wherein the functionalization comprises a thioalkylene linker bound to the support surface and the thioalkylene linker is coupled to a moiety derived from a ligand, wherein the ligand includes a terminal alkenyl and at least one first functional group configured to bind to at least one predetermined target species.
