The disclosure concerns an aqueous composition comprising carbon nanotubes and a surfactant, characterized in that the carbon nanotubes are single-wall hydrophobic nanotubes and in that the surfactant is chosen among electropolymerizable surfactant monomers of formula (I): X—Y—Z   (I) wherein: X is an electropolymerizable moiety selected from the group consisting of pyrrole, acetylene, phenol, aniline, thiophene, carbazole, indole and azulene Y is a hydrophobic hydrocarbon chain and Z is a polar group selected from the group consisting of quaternary ammonium salts, alkylphosphonates and sulfonates. The disclosure also relates to a method for the preparation of an aqueous composition as described above, comprising the following steps: i) solubilisation of the surfactant monomer ii) addition of the single-wall carbon nanotubes in the aqueous solution comprising said surfactant monomer, (iii) sonication of the resulting solution, and, optionally (iv) addition of a protein.
