The problem is that even benign materials can have unexpected outcomes that depend on their nano-structural properties. Carbon is safe, but carbon nanotubes can form cysts [1] and cause brain damage in fish [2].

- durkie 14y agoYou're absolutely right -- there are some materials that would be very bad candidates here. I was pointing out only that this can be achieved with structure only (no additional hydrophobic/hydrophilic chemicals), and that it can be done with materials that have already proven themselves inert when ingested in nano-scale particle sizes.
