Synthesis of Silk Fibroin Micro‐ and Submicron Spheres Using a Co‐Flow Capillary Device

A custom-made co-flow capillary device is used to synthesize monodisperse silk fibroin micro- and submicron-spheres with diameters tunable over a wide range of sizes. A model drug release is examined and control of degradation kinetics is obtained by changing sphere diameter.
