Abstract:
Despite the rapid growth of microfabrication technologies over the past decades, many desirable microstructures remain difficult or even impossible to create, especially when the structures are three-dimensional and/or composed of multiple components that feature different materials that must be arranged in a highly specific pattern. Multiphoton absorption polymerization (MAP) offers one solution to this problem. I will discuss the basic principles of MAP and our efforts to extend the capabilities of this technique to create ever finer features. I will also discuss aqueous MAP photoresists that can be used in combination with different techniques for nanomanipulation to create such structures. Nanomanipulation techniques can also be used to place micro- or nanoscale components in desired locations in three dimensions, after which they can be immobilized in place using MAP. This toolbox of techniques offers the capability of creating a broad range of new structures and devices featuring polymeric, inorganic, metallic and biomolecular components.
Bio:
Dr. John Fourkas is the Millard Alexander Professor of Chemistry at the University of Maryland, College Park. He earned a BS and an MS in Chemistry from the California Institute of Technology and a PhD in Chemistry from Stanford University. He is a Fellow of the APS, the OSA, and the AAAS. His work is focused on applications of nonlinear optics in the study and manipulation of matter, particularly at the nanoscale. His research group has extensive experience in the development of multiphoton lithographic techniques and their application to a broad range of problems.
