Abstract
A method for purification of a target in a solution includes providing a target in a solution, the solution comprising one or more contaminants, providing a polymer conjugate in the solution, wherein the polymer conjugate is configured to specifically bind the target, incubating the solution at a first temperature to facilitate binding of the polymer conjugate to the target, providing an environmentally-responsive block copolymer in the solution, wherein the environmentally-responsive block copolymer comprises one or more of an ethylene oxide (EO), a propylene oxide (PO), or an EO/PO block copolymer, and heating the solution comprising the environmentally-responsive block copolymer and the polymer conjugate bound to the target at a second temperature to initiate a liquid-liquid phase separation, wherein the liquid-liquid phase separation produces an aqueous phase and a liquid polymer phase, and wherein the liquid polymer phase comprises the polymer conjugate bound to the target.
