Silk-fibroin Micro-drug Delivery Systems

This chapter focuses on silk fibroin micro-drug delivery systems, with particular attention to microparticles/microspheres, microcapsules, microneedles and microfibers. Their production by different techniques, properties and applications, both in vitro and in vivo, are described. Moreover, their more recent employment for the delivery of drugs, and tissue engineering and regenerative medicine purposes is reported.
