In this communication, we report the synthesis of an amino-functionalized ionic liquid (AFIL) and its application as building block in the construction of new functional nanomaterials. This AFIL has been used as surfactant in the synthesis of gold nanoparticles (Au NPs) and in the development of functional CNTs/IL hybrid nanomaterials by mixing the AFIL with multi-walled carbon nanotubes (MWCNTs). The presence of an amine group in the ionic liquid provides to the resultant nanomaterial with new opportunities in several applications in the nanobio field.
