Thermosetting particles and their manufacturing processes can be provided. In these, the particles can have a spherical or fibrous shape. A reaction mixture comprising a thermosetting resin, a crosslinking agent, a surfactant and a solvent can be provided. The reaction mixture may be an emulsion, suspension or dispersion that may optionally be sprayed or electrospun. Crosslinking of the resin can be performed by adding an initiator to form polymerized particles or by exposing the reaction mixture to heat and / or radiation. The particles can be subjected to drying, sintering, pyrolized or carbonization and / or impregnation according to the active pharmaceutical invention. |
