The largest obstacle the medical field and the drug industry face today are the lack of testing options for new drugs and the latest treatments. Of the many animal models and other experimental methods that exist, none simulate the complexity of the microenvironments found in the human body like the gut or the mouth. This makes the testing and distribution of the most novel and potentially life saving treatments difficult and time consuming. At the same time, these testing methods may not provide the most accurate results of how treatments will affect the human body.
