The process typically involves the following steps: 1. Dissolution of the polymer and the active pharmaceutical ingredient (API) in an organic solvent. 2. Emulsification of this solution into an aqueous phase containing a surfactant to stabilize the droplets. 3. Evaporation of the organic solvent, leading to the formation of solidified nanoparticles. 4. Collection and purification of the nanoparticles.
