Microbead And Nanofiber Based Controlled Drug Release System

摘要

Various examples are provided for controlled drug release over an extended period of time. In one example, a controlled release system includes a multilayer membrane including a first biocompatible nanofiber layer; a microbead layer disposed on the first biocompatible nanofiber layer, the microbeads comprising a releasable agent; and a second biocompatible nanofiber layer disposed over the microbead layer. The first and second biocompatible nanofiber layers support the microbead layer and provide a diffusion barrier that can control a release profile of the releasable agent.
