An example is the templating of domains in block copolymers (top). We have analysed the templating accuracy for lithographic applications. We also templated pores in anodic alumina and used the resulting porous film to create thin-walled magnetic tubes (bottom) which may be useful in magnetic fluids or drug delivery. We templated the formation of metal dots within regularly-spaced inverted pyramids: these can serve as nucleation sites for arrays of nanotubes. 200 nm 200 nm

2. Nanostructured Surfaces with Long-range order for Controlled Self-AssemblyC.A. Ross, H.I. Smith, C.V. Thompson, F.M. Ross; MIT and IBM, DMR0210321, 8/1/2002 – 7/31/2006 Education: Three graduate students (Mike Walsh, Amanda Giermann, Ram Krishnan), two postdocs (Joy Cheng and Kornelius Nielsch) and an undergraduate researcher (Mariana Shnayderman) have worked on this project. Our work spans many self-assembling systems, and applications such as data storage, and we have worked with a range of collaborators from Spain, the Netherlands, Singapore and the US. Two of the PIs are writing a graduate course on nanoprocessing of materials. Outreach: Working with Felice Frankel, a science communicator/artist at MIT, Mariana developed a set of animations designed to explain the concept of templated self-assembly to the public.
