Nanocopying as a Means of 3D Nanofabrication: Scope and Prospects

The use of nanosized templates to fabricate three-dimensional architectures in the nanometer regime is still a largely unexplored field of nanotechnology. Positive and negative copying of molecules and nano-sized objects by the surface sol-gel process is useful for this purpose. The authors here give account of the techniques available to date, along with their advantages and disadvantages, is outlined.
