Abstract
A method of separating a target biological species from a fluid is disclosed comprising contacting the fluid with a ligand-functionalized polymer comprising: a water soluble or water dispersible aminopolymer functionalized with guanidinyl groups; whereby a complex comprising the functionalized substrate and the target biological species is formed.
Claims21
A method of separating a target biological species from a fluid comprising:
- contacting the fluid with a
- substrate having a coating on a surface thereof of a
- ligand-functionalized polymer comprising
- a water soluble or water dispersible aminopolymer functionalized with guanidinyl groups;
- whereby a complex comprising the ligand-functionalized polymer and the target biological species is formed, and separating the complex;
- wherein said target biological species selected from biomacromolecules and microbiological species,
- wherein the substrate is selected from a film, or a woven or nonwoven web.
