Claim Text:
1. A method of monitoring a location of a nanoparticle within a material, including the steps of: providing at least one nanoclay particle including organically modified montmorillonite (o-MMT); reacting the at least one nanoclay particle including o-MMT with a solution including mercaptosilane to convert a hydroxyl of the o-MMT to a thiol moiety and produce a mercaptosilane modified nanoclay particle including the thiol moiety; reacting the mercaptosilane modified nanoclay particle with a thiol-reactive dye including a fluorescent tag to attach the fluorescent tag to the thiol moiety of the mercaptosilane modified nanoclay particle with a covalent bond to form a fluorescent-labeled nanoclay particle; determining a fluorescence of the fluorescent-labeled nanoclay particle; inserting the fluorescent-labeled nanoclay particle into the material; depositing the material in an aqueous solution; and detecting a movement of the fluorescent-labeled nanoclay particle from the material to the aqueous solution.
