Nathan, David did not say the nanoparticles were non organic. I googled nanoparticle and the Wiki just says it means particles of a certain size.
"particles between 1 and 100 nanometres (nm) in size. In nanotechnology, a particle is defined as a small object that behaves as a whole unit with respect to its transport and properties. Particles are further classified according to diameter."
The definition of nanotechnology covers a lot of areas too.
"Nanotechnology as defined by size is naturally very broad, including fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, molecular engineering, etc."
Wouldn't David be talking about the molecular biology and organic chemistry nanotechnology sciences, since that is what he was experimenting with? Those are organic. Here is how Wikipedia describes those.
"Molecular Biology concerns the molecular basis of biological activity between biomolecules in the various systems of a cell, including the interactions between DNA, RNA, and proteins and their biosynthesis, as well as the regulation of these interactions."
"Organic Chemistry is a chemistry subdiscipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms."
