Abstract

(Figure Presented) The separate encapsulation of nanoparticles (NPs) and pancreatic islets in an alginate capsule-in-capsule (CIC) structure prevents the nanoparticles being toxic to the cells while housing a high payload of nanoparticles for imaging purposes (see picture). The CIC-encapsulated islets showed an improved insulin secretion over cells encapsulated in single capsules and their transplantation into diabetic mice restored normal glycemia.
