Abstract

There is an increasing need for tools that can create complex 3D arrays of organic material, with control over chemical composition, and with sub-1 μm feature diameters. These substrates could be used for various emerging applications ranging from coatings, electronics, tissue engineering, sensors, and merging the biotic with the abiotic. While industry is incredibly adept at creating complex architectures with sub-100 nm feature dimensions of hard inorganic materials with the tools of microfabrication, there exists no such similar platform for organics. Research in the Braunschweig Group is devoted to creating just such a technology, where the chemical composition of each feature across a surface can be arbitrarily controlled in 3D with sub-1 μm resolution. This lecture will discuss recent advances from our group in surface chemistry, instrumentation development, and surface analysis to create new cleanroom-free, desktop printing solutions that will enable new research where interactions at the solid-organic interface have a critical role.

Biography

Adam B. Braunschweig is a Professor in the Nanoscience Initiative team at the CUNY Advanced Science Research Center. He was formerly an Assistant Professor in the Department of Chemistry at the University of Miami and at New York University before deciding to take his talents to Manhattan. He earned his B.A. in Chemistry at Cornell University (2001) and his Ph.D. in Organic Chemistry at the University of California – Los Angeles (2006). He later served as a postdoctoral researcher in nanotechnology at the Hebrew University of Jerusalem and as an NIH postdoctoral researcher in cancer nanotechnology at Northwestern University. He taught as an NSF GK-12 Fellow in Fremont High School in Los Angeles.
