The Creation Of Organic And Biological Nanostructures At Surfaces Using Scanning Probe Nanolithography, B. L. Weeks, Chin Li Cheung, J. J. De Yoreo

Barry Chin Li Cheung Publications

As the size of microelectronic devices continues to shrink and the desire to build in hierarchical structures of organic and biological materials grows, control of the chemistry and structure of materials at the molecular level will become increasingly important. Conventional lithographic techniques to pattern polymeric thin films are beginning to reach their resolution limit and several alternative "bottom-up" strategies have emerged that use the scanning probe microscope to manipulate matter at the atomic or molecular scale. Of these new scanning probe nanolithography (SPN) techniques, dip-pen nanolithography (DPN) [I] and scanning probe nanografting (SNG) [2] are particularly promising.

The DPN methodology …
