Nanoparticles are now an indispensable material for science and technology such an in materials, medicals, and cosmetics areas. Controlling the dispersion stability of nanoparticles in various liquid media or solid matrix materials is an essential issue to control the properties of the final products. In this paper, I will briefly review the surface modification techniques to overcome the difficulties of handling nanoparticles in liquids. Many kinds of post-synthesis surface modification, such as adsorption of surfactant with various molecular structures and layer by layer surface reaction of coupling agents, will be introduced. Finally, some examples of nanoparticles for the application of new advanced composite material will be demonstrated.
