In the preparation process, silk protein was first oriented deposited on the surface of silica microspheres by electrophoretic deposition technology, and then cross-linked with EDCNHS to form macroporous microcarriers. The morphology and internal structure of the carriers were observed by scanning electron microscopy and transmission electron microscopy, and it was found that the surface of the microspheres was uniformly covered with silk protein, which overlapped and connected to form a pore structure. At the same time, Fourier transform infrared spectroscopy and X-ray diffraction analysis confirmed the successful cross-linking reaction and the crystalline state of the carrier. Finally, the drug release performance of the carrier was evaluated, and the results showed that the prepared microcarriers had controllable and sustained drug release.Keywords: silk protein, cross-linking agent, macroporous microcarriers, drug release
