    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.

    Abstract: Macroparticulates may be formed through at least partial self-assembly by reacting an epoxide-containing (meth)acrylic polymer or copolymer with a compound bearing a nitrogen nucleophile, such as iminodiacetic acid or ethylenediamine. When the epoxide-containing (meth)acrylic polymer or copolymer is formed into a predetermined shape before reaction with the compound bearing the nitrogen nucleophile, a profile of the predetermined shape may be at least partially maintained and undergo expansion in the course of forming the reaction product, thereby producing macroparticulates having a larger volume than the predetermined shape itself. An internal cavity may be formed when generating the macroparticulates in this manner. Optionally, a hexasubstituted benzene or a supramolecular receptor may be adhered to a surface portion of the macroparticulates, either covalently or non-covalently. The compound bearing a nitrogen nucleophile may be further modified to form one or more functionalities capable of binding an analyte.
