Abstract
Polymeric microstructures and nanostructures can be prepared with use of a tip to pattern a surface. A tip can be used to pattern a structure which can initiate polymerization. The structure can be then exposed to monomer to induce polymerization at the structure. Alternatively, a tip can be used to pattern a surface with a monomer in which the surface is treated with polymerization catalyst so that polymerization occurs at the patterning site. Ring-opening metathesis polymerization can be carried out with use of the tip to control the polymerization. The tip can be a sharp tip as used in for example an atomic force microscope tip. Norbornene types of monomers can be used. Biological macromolecules can be also prepared.
