The functionalization of halloysite nanotube (HNT) surfaces with aminosilanes is an important strategy for their further decoration with organic mols. to obtain hybrid inorganic-organic nanoarchitectures to be used in catalysis and drug delivery. The exact quantification of amino groups on the surface is an important aspect in view of the obtainment of systems with a known number of loaded mols. In the present study, we describe a simple and reliable method for the correct quantification of groups present on HNT surfaces after their reaction with aminopropyltriethoxysilane (APTES). This method, applied for the first time to HNT chem., was based on the use of Fmoc groups as probes covalently bound to APTES and quantified by UV-Vis after release from the HNT-APTES-Fmoc system. Interestingly, this method showed great accordance with the already employed quant. thermogravimetric anal. (TGA), with some benefits such as simple and non-destructive procedure, besides the possibility to monitor the deprotection reaction.
