Overview
Smart drug delivery systems administer drugs, where they are needed, when they are needed and at the right concentration. Thus diminish the side effects and the amount of drugs needed. It could eventually be used to treat a wide range of diseases, but especially tumors. The idea to target the drug delivery is to increase the concentration of the drug at the target site while keeping it to a minimum in the rest of the organism. One big drawback of smart drug delivery is that it doesn't exist for many drugs, it needs to be developed for each drug separately and that is quite expensive.
