Exercise 11

Consider that you are designing a therapy to deliver a biomolecule or drug to a tissue over an extended period of time.
a. What is the key criterion that you will look for in a polymer to provide this extended delivery time? (Be specific.) Why?
b. Would polyanhydride (which is highly hydrophobic) or polylactic acid (which is considerably less hydrophobic) be better for this application? Why?
