Your encapsulation device is designed to deliver insulin, which needs to travel systemically through the blood stream. You modeled the drug delivery from your implanted device (as in class), resulting in the graph below. Assume that the insulin released from the surface of the device is 3 mg, and your targeted therapeutic dose to be delivered to the blood stream is 1.5 mg; how far can the implant be from the nearest blood vessel to achieve your targeted dose? Why does the concentration of the agent drop exponentially away from the surface of the device in the model?
