Drug delivery is an advanced approach in which patients are distributed narcotics in a targeted order, increasing the concentration of the medicament delivered only for the targeted body portion of their concern such as tissues and cells, which increases treatment effectiveness by minimizing administered medications side effects. The intrinsic value of this procedure means that the necessary medication with its decreased dosage has been given and its side effect has been reduced. This fundamental benefit of the smart drug delivery system is also the foundation of the therapeutics and diagnostics research and advancement in the clinical and pharmaceutical sectors. In essence, targeted/smart drug delivery is to help the drug molecule enter the intended site ideally.
