Nanotechnology: Newer Approach in Insulin Therapy.

Insulin is a peptide hormone released by pancreatic beta cells. An autoimmune reaction in diabetes mellitus type 1 causes the beta cells to die, preventing insulin from being produced or released into the bloodstream; that impacts 30 million people globally and is linked to shortened lifespan due to acute and chronic repercussions. Insulin therapy aims to replicate normal pancreatic insulin secretion, which includes low levels of insulin that are always present to support basic metabolism, as well as the two-phase secretion of additional insulin in response to high blood sugar - an initial spike in secreted insulin, followed by an extended period of continued insulin secretion.
