By 2030, diabetes will be the 7th leading cause of premature mortality worldwide, according to the World Health Organisation. The application of nanotechnology in medicine holds many possible advantages and over the past few decades, there has been huge progress in its utilisation. Nanotechnology is widely applied for cancer treatment and other diseases but, the use of it for diabetes treatment is now starting to flourish. This book presents the latest developments of nanomedicine for the treatment of different facets of diabetes and related disorders. With a multidisciplinary approach, chapters focus on previously overlooked topics in glucose sensing, insulin delivery and secretion, bioimaging and transplantation of islets. This book is suitable for researchers of nanomedicine, nanotechnology and diabetes looking into the emergence of new approaches for the treatment of this life-threatening disease.
