18. To avoid ambiguity, we reserve the term "dendrimer-encapsulated nanoparticles" to refer to those cases in which nanoparticles are contained within individual dendrimers. We propose the term "dendrimer-protected nanoparticles" to refer to the far more general case in which no such restriction is implied.
