Vulnerable Spaces (IMAGE) DOE/Sandia National Laboratories Caption The protective capabilities of a chain-link molecular coating are lessened when, instead of attaching to a flat surface to form an unbroken wall (fig. 1), the radius of the nanoparticle is so small that the extreme surface curvatuere opens spaces between the protective molecules (fig. 2).
