Guanidinyl ligand-functionalized polymers, methods of making the same, and substrates bearing a grafted coating of the ligand-functional polymers are described. The grafted polymer has the requisite affinity for binding neutral or negatively charged biomaterials, such as cells, cell debris, bacteria, spores, viruses, nucleic acids, endotoxins and proteins, at pH's near or below the pI's of the biomaterials.

The current invention provides a novel method to synthesize a mono-disperse non-porous polymer particles with a unique gradient composition from the core to the shell. In particular, The present invention offers the flexibility to design the chemical and physical properties of different sections of the particle. This flexibility allows for significant latitude in the design of particles for analyzing a large variety of samples in different fieldsthrough using these particles in different chromatography techniques including, but not limited to, ion exchange HPLC (e.g., bio-separation at different modes), reversed-phase HPLC, narrow bore and capillary HPLC, hydrophilic/hydrophobic interaction liquid chromatography, capillary electrochromatography separation, and two dimensional liquid chromatography.

A carrier for adsorption a compound, comprising a support; and a shrink-fitted monolithic body attached to and surrounding at least a portion of the support. The monolithic body can be porous and configured to bind compounds in a solution either for the isolation or depletion of the compounds from the solution.

Disclosed is a method for making a composite material, which is of particular use in wound treatment. The composite material has a hydrophilic polyurethane foam material with a first polyurethane polymer; a hydrophilic fiber material having a second polymer, wherein said second polymer is not a polyurethane polymer and wherein said fiber material is capable of absorbing and retaining a fluid. The first polymer is covalently bonded to the second polymer.
