This medical-grade polyester is currently used in teeth guards that kids and adults wear at night, in tiny tubes used to guide the growth of damaged nerve fibers and in surgical sutures.  Researchers are also looking at PCL’s potential as an implant to deliver medications directly to the eyes and to tumors and as a scaffold for growing human tissue.  PCL may be an ideal package for islet cells, the studies note, because it can be used to create thin, flexible membranes with pores that let in glucose and nutrients, let out insulin and exclude bigger immune-system molecules.

Diabetes is a number of diseases that involve problems with the hormone insulin. Normally, the pancreas (an organ behind the stomach) releases insulin to help your body store and use the sugar and fat from the food you eat. Diabetes can occur when the pancreas produces very little or no insulin, or when the body does not respond appropriately to insulin. As yet, there is no cure. People with diabetes need to manage their disease to stay healthy.
