Glucose-Responsive Insulin Delivery by Microneedle-Array Patches Loaded with Hypoxia-Sensitive Vesicles

Methods Mol Biol. 2017:1570:251-259. doi: 10.1007/978-1-4939-6840-4_17.

Abstract

In this chapter, we describe the preparation of glucose-responsive vesicles (GRVs) and the fabrication of GRV-loaded microneedle-array patches for insulin delivery. The GRVs were formed of hypoxia-sensitive hyaluronic acid (HS-HA), the synthesis of which is presented in detail. We also describe the procedure to evaluate the in vivo efficacy of this smart patch in a mouse model of chemically induced type 1 diabetes through transcutaneous administration.

Keywords: Diabetes; Drug delivery; Glucose-responsive; Hypoxia-sensitive; Microneedle.
