Abstract

Nanoparticles are the only materials small enough to target cells in the body, and therefore are crucial to targeted drug delivery. Issues with the synthesis, consistency, and bioactivity of these molecules are still being addressed, but base on current proof of concept studies there is a reason to believe that the ‘holy grail’ of targeted drug delivery might someday be achieved using nanoparticle-based systems.
