| Two major contributions that have resulted from the increased focus on “nanotechnology” since the 1990s have been the enabling of both top-down and bottom-up functional device fabrication in the mesoscale regime; and, the enhanced ability to use nanostructured surfaces/interfaces for the collective control of the molecular interactions and reactions that define macroscale properties and processes. The latter includes both the creation of new nanostructured materials and a new perspective on what might be done with older, well-known nanostructured surfaces. The latter also has reinforced the convergence of nanoscale chemistry with biology, where mesoscale interfaces and structures with built-in molecular nanostructured features are dominant. At the small end of the dimensional scale, there is a long and very successful technology history for nanostructured materials. For example, the reactant, transition state and product selectivity of 3-D nanoporous zeotype structures has resulted in a classic nanotechnology (before this term was invented) success story at the sub-mesoscale level (< 20 Angstroms) that has had a huge commercial impact over the past 50 years. This talk will give a few selected examples of the use of old and new nanostructured materials to control biological and chemical reaction systems. |
