Fabrication of glucose-sensitive protein microcapsules and their applications

The layer-by-layer (LbL) technique has been widely used to construct different types of microcapsules based on the electrostatic interaction between charged polymers and proteins. However, in this review, we will mainly focus on the fabrication of microcapsules by using a covalent cross-linking method. The structure and properties of the assembled microcapsules are described and their potential applications in glucose-sensing and glucose-sensitive drug delivery are introduced.
