Abstract Application of nanomaterials has been extended from industrial application such as energy, chemical engineering, optoelectronics, machinery and etc, to consumer goods such as cosmetics, metical products, textiles and home applications. However, with widely use of these nanomaterials, these issues of environmental safety and human health are more important in the world. Especially silver nanoparticles, because of its significant antimicrobial efficacy, it has been widely used in sprays, clothing, daily necessities, household appliances and building materials. Whether these products with silver nanoparticles are poisonous or not, these issues still lack scientific evidences. Therefore, the national labor safety organization (such as the United States National Institute for Occupational Safety and Health, NIOSH) and OECD (Organization for Economic Co-operation and Development) agreed that development of reference materials was a important to environmental safety and health-related researches. For example, U.S. NIST started to developed a variety of nano reference materials and organized relative activities. In order to provide the standard materials in Taiwan, we synthesized silver nanoparticles for reference material. The silver nanoparticle was synthesized by using silver nitrate as a precursor of Ag. Silver nitrate was dissolved in starch solution together with arginine which reduced the silver ions to silver nanoparticles. Beside, we used the microwave as a heating source to obtain more uniform nanoparticles. The mean particle size of silver nanoparticles determined from image analyses of SEM micrographs was 14.1 nm. The silver concentration of the solution was measured by inductive couple plasma optical emission spectroscopy. On the other hand, because the process was bio-compatible, we also cooperated with National Health Research Institute, R.O.C. for toxicity test. The results will be presented in the future.
