Powder technology has already extended its scope of interest to nanoparticles with novel properties and functionalities. Since the establishment of the National Nanotechnology Center (NANOTEC) in 2003, research activities in nanotechnology have shot up remarkably, including the production of nanoparticles via physical, chemical and biological methods. This article reviews and introduces recent works on nanoparticle production in Thailand, especially NANOTEC and her nation-wide network of Centers of Excellence. The categories of nanoparticles of interest extend from metal and zinc oxide nanoparticles to carbon nanoparticles and titanate nanostructures. However, thin films and nanofilms lie beyond the scope of this review. (c) Koninklijke Brill NV, Leiden and Society of Powder Technology, Japan, 2008
