Mesoporous silica nanoparticles (MSNs) have been widely used as drug carriers in the diagnosis and treatment of diseases due to their specific characteristics, which include a large surface area, ordered mesoporous structures, easy surface modification and feasible sustained release action for encapsulated drugs. With the research development of MSNs, the biodegradability and removability of mesoporous silica nanomaterials have attracted considerable attention in the clinical application of the MSNs-based formulations. This paper was prepared to emphasize the preparation approaches of biodegradable mesoporous silica nanoparticles through the metal oxide doping method and the organic compound doping method. We discussed the biodegradable mechanism and process of such nanoparticles, and finally, provided an insightful and helpful review of the prospective application of the biodegradable mesoporous silica nanoparticles in medical field.
