Lycopodium particles which are spores of the plant Lycopodium clavatum were exposed to cold oxygen and nitrogen plasma irradiation. Wetting properties of the particles changed dramatically from hydrophobic to hydrophilic. Plasma treatment allowed obtaining stable water suspensions of lycopodium. Plasma treatment did not affect the morphology of lycopodium particles. The reported results open the way for surfactants-free manufacturing suspensions of hydrophobic particles.
