The beauty of nano-technology is mainly dependant on the size of the particle. As the size decreases to nano range (1- 300 nm), the surface area of the particle increases and thus imparting the nano-particle the enhanced chemical, physical and biological properties. Nano-technology is an emerging science at present and is the science for the future development. It has got a wide range of scope and applications in the fields of medical science, space science, agriculture, chemical engineering, genomics and so on. As such there is no renowned bodies for its regulations internationally but at a country level some of the developed and developing nations are regulating through its existing institutions. OECD, EU, FDA, Health Canada, etc. are some of the working regulatory bodies in the field of nano-technology. Its application in the field of textile sector is not explored much but it is mainly used for finishing of the fabric or imparting specific properties like anti-microbial, fire resistance, UV protective clothing, etc. by coating the fabric with nano-particles. A huge scope and tremendous gap are existing with respect to its regulation for manufacturing, sell, transportation, storage, handling of nano-products, etc. In future, its application in the field of textile can be explored voraciously.
