While nanoparticles sound like a recent discovery, these tiny structures have been used for centuries. Nanoparticles can be produced using either physical or chemical methods, though physical methods are advantageous due to the absence of organic contaminants commonly introduced by chemical methods. However, uniformly sized nanocubes are difficult to produce in sufficient quantities by physical methods. Now researchers have recently discovered a new approach to overcome this problem.
