Figure 1.

Schematic representation of nanoparticles in a spectrum of inorganic/organic molecules, macromolecules, and large molecular assemblies such as viruses and cells, measured in nanometers of different biological molecules (A). Distinct properties are shown as: size range (B); water affinity (C); and surface charge (D). Parts of the figure were drawn using pictures from Servier Medical Art.
