With Diabetes being the leading cause of death and number of cases higher than ever, this research on “glucosensitive insulin” is a significant contributions to science. Author clearly identified the precise need to improve diabetic care and researched how to create a novel pulsatile insulin delivery system. This early ground breaking work on pulsatile insulin delivering gels is novel, scientifically challenging, and medically relevant. Since the work delves into feedback controlled drug delivery, novel drug delivery, smart gels and artificial pancreas, all topics that are in the forefront of cutting edge drug delivery and diabetes research, it will be enjoyed by readers from Biomedical community to Drug delivery and Pharmaceutical industry to Polymer scientists and many more. A must read for all!
