Abstract: A method of fabricating shaped particles is disclosed. The method involves generating a plurality of droplets within dispersion media (e.g., oil and surfactant), the plurality of droplets formed from a mixture of precursor materials that are in a miscible state. A stimulus or change of conditions is then introduced to the droplets so as to cause the mixture of precursor materials to become immiscible and phase-separate from one another. The phase-separated droplets are then crosslinked to form shaped particles. The stimulus or change of conditions may include one or more of the following: a change in temperature, a change in pH, a change in osmolarity, a change composition of the droplets, a change in the composition of the dispersion media. The shaped particles may be washed to remove un-crosslinked material and one or more affinity capture agents may be immobilized onto the shaped particles.
