The Rosetta Stone ia a stone with writing carved into it. It was found in Egypt in 1799, and was crucial in understanding the meaning of the Ancient Egyptian writing system called hieroglyphics. In fact, it had three pieces of writing on it that said the same thing in three diferent languages. One was in an Ancient Egyptian script called demotic, the other two languages were hieroglyphics and Ancient Greek. The interpretation of the data o experimental studies on the toxicity of engineered nanomaterials arte still at the hieroglyphics stage as far as their translation to humans is concerned. Their Rosetta stone has to be found yet.

The engineering of clinically viable targeted nanocarriers requires a deep understanding of ligand‐receptor interactions; an accurate characterization of receptor distribution on cellular surfaces; and a precise control over nanocarrier architecture and spatial display of targeting ligands.
