Abstract
To provide a porous particle with which non-specific adsorption is hardly generated although the porous particle is a synthetic polymer-based particle, the mechanical strength is high, and the dynamic binding capacity is high in a case where a ligand is bound to the porous particle; and a method for producing the same. A method for producing a porous particle, including the following steps 1 and 2; (step 1) dissolving at least one or more of polymers selected from the group consisting of a vinyl alcohol polymer and an ethylene-vinyl alcohol copolymer in an aqueous solvent to prepare a polymer solution; and (step 2) dispersing the polymer solution in a non-aqueous solvent to form a W/O emulsion.
