Gizmag: Injectable nanoparticles maintain normal blood-sugar levels for up to 10 days.

Fascinating technology featured in Gizmag & posted by someone HERE.
The nano-network that releases insulin in response to changes in blood sugar
"The injectable nano-network is made up of a mixture that contains nanoparticles with a solid core or insulin, modified dextran (which is commonly used to reduce blood viscosity), and glucose oxidase enzymes. When exposed to high levels of glucose, the enzymes convert glucose into gluconic acid, which breaks down the modified dextran to release the insulin. The gluconic acid and dextran, which are biocompatible, dissolve in the body, while the insulin brings the glucose levels under control.

The nanoparticles are given a positively or negatively charged biocompatible coating so that when they are mixed together, they are attracted to each other to form a “nano-network.” The positively charged coatings are made of chitosan, a material found in shrimp shells that has also found applications in self-healing car paint, while the negatively charged coatings are made of alginate, a material normally found in seaweed."

Wow! Cool bananas!

Cool beans indeed!

Now I'm relieved to hear...that cool bananas exists on and that it means cool beans.
