    Abstract: Methods of treating a substrate, e.g., forming a coating on the substrate, are described. The method may include applying a solution comprising a multifunctional molecule or a multifunctional-polymer molecule to at least a portion of a surface of the substrate. The surface may comprise a metal or metal alloy and the multifunctional molecule or a multifunctional-polymer molecule may bond to the surface via at least one sulfur group of a plurality of sulfur groups of the multifunctional molecule. The method may include combining the multifunctional molecule with a polymer molecule to form the multifunctional polymer molecule before or after applying the solution. The polymer molecule may bond to an internal carbon group or a terminal sulfur group of the multifunctional molecule.

    Abstract: In some aspects, the present disclosure pertains to a polymer that comprises a plurality of polymer arms, wherein a first portion of the polymer arms comprise a reactive end group and wherein a second portion of the polymer arms comprise a branched end group that comprise a plurality of covalently attached diagnostic and/or therapeutic groups, which may be, for example, radiocontrast groups or radioactive groups. Other aspects pertain to a system that comprises (a) a first composition comprising such a polymer and (b) a second composition comprising a multifunctional compound that comprises reactive functional groups that are reactive with the reactive end group of the multi-arm polymer. Still other aspects pertain to a crosslinked reaction product of (a) such a polymer and (b) a multifunctional compound that comprises functional groups that are reactive with the reactive end group of the multi-arm polymer.
