Core-shell hydrogel microcapsules for improved islets encapsulation

Adv Healthc Mater. 2013 May;2(5):667-72. doi: 10.1002/adhm.201200341. Epub 2012 Dec 3.

Abstract

Islets microencapsulation holds great promise to treat type 1 diabetes. Currently used alginate microcapsules often have islets protruding outside capsules, leading to inadequate immuno-protection. A novel design of microcapsules with core-shell structures using a two-fluid co-axial electro-jetting is reported. Improved encapsulation and diabetes correction is achieved in a single step by simply confining the islets in the core region of the capsules.
