Iran’s second proposed international standard on nanotechnology approved

'Determination of muramic acid as a biomarker for silver nanoparticles activity' standard which was proposed three years ago by Standardization Committee of Iran Nanotechnology Initiative Council to the Nanotechnology International Standardization Committee (ISO/TC229) was approved in the final stage of voting (DTS stage) and will be published in the near future. The compilation and development of the standard began three years ago by a university team with the support of Iran Nanotechnology Initiative Council by carrying out laboratorial research. During these years, various experts from different countries were introduced to supervise the compilation of the standard. The suggestions of the experts were evaluated and approved by the project supervisor of the proposed standard. A new method has been presented in the standard, which can quantitatively and precisely determine the activity of silver nanoparticles. The standard can be used for the determination of antibacterial properties of products based on silver nanoparticles. Only a number of countries, including the US, Britain, China, South Korea, Germany, France, Japan, and Iran, have so far succeeded in the compilation of a standard in Nanotechnology International Standardization Committee (ISO/TC229). Another standard entitled 'Definitions for the evaluation of science, technology, and innovation indices' is currently being compiled in ISO under the supervision of Iran.
