A high-speed vibration milling (HSVM) method was applied to synthesize water dispersible single-walled carbon nanohorns (SWNHs). Highly reactive free radicals (HOOCCH2CH2 center dot) produced from an acyl peroxide under HSVM conditions react with hydrophobic SWNHs to produce a highly water dispersible derivative (f-SWNHs), which has been characterized in detail by spectroscopic and microscopic techniques together with thermogravimetric analysis (TGA) and dynamic light scattering (DLS). The carboxylic acid functionalized, water-dispersible SWNHs material are versatile precursors that have potential applications in the biomedical area.
