1. A composition comprising:

  • a functionalized silicate nanoparticle comprising a reaction product ofa silicate nanoparticle; and

    a functionalization compound comprising quaternary ammonium salt, quaternary phosphonium salt, alkoxy silane, halide, guanidine, guanidinium salt, biguanidine, biguanidinium salt, sulfonium salt, or a combination thereof; and

    a fluid,wherein the functionalization compound includes a chemical group comprising;

    a first portion, the first portion being directly bonded to the silicate nanoparticle in the functionalized silicate nanoparticle; and

    a second portion comprising an aromatic moiety or a combination of an aromatic moiety and a nonaromatic moiety, andthe composition is effective to remove an asphaltene particle from a substrate comprising a metal, composite, sand, rock, mineral, glass, formation, downhole element, or a combination thereof,wherein the silicate nanoparticle comprises a silsesquioxane, cyclosilicate, inosilicate, nesosilicate, phyllosilicate, sorosilicate, tectosilicate, or a combination thereof,
