Bottom-Up Methods for Making Nanotechnology Products
www.azonano.com › articleDec 14, 2004 · Methods using supercritical fluids are also powerful for the synthesis of nanoparticles. For these methods, the properties of a supercritical fluid (fluid forced into a supercritical state by regulating its temperature and its pressure) are used to form nanoparticles by a rapid expansion of a supercritical solution.
