The interface between different fields is believed to be fertile ground for breakthrough research. The interface between the emerging fields of biotechnology and nanotechnology is particularly interesting. The possibilities for new fruit are diverse: biotechnology offers new approaches for self-assembly of structures at the nanoscale, while nanotechnology offers new methods for probing and accessing biological systems. In this talk, I will discuss research in this new frontier in my group, including 1) self-assembly of 2D nanocomponent arrays by in situ hybridization to DNA scaffolding, 2) alkanethiol//oligo(phenylene-ethynylene) molecular junctions exhibiting negative differential resistance, and 3) nanoscale MOSFET?s with carbon nanotubes channels and organic molecule gate dielectrics. The possibilities for ?turning the table? to exploit such nanostructures for sensing and imaging biological systems will also be discussed.

Richard A. Kiehl received the B.S., M.S., and Ph. D. degrees from the School of Electrical Engineering, Purdue University. From 1974 to 1980 he was a member of technical staff at Sandia National Laboratories, where he initiated studies on optical control of microwave semiconductor devices. In 1980 he joined AT&T Bell Laboratories, Murray Hill, as a member of technical staff. He was a leading contributor to the Bell Labs research on heterostructure electronics, particularly heterostructure field-effect transistors. In 1985 he joined IBM as research staff member at the T. J. Watson Research Center and focused his work on III-V and SiGe-based heterostructure CMOS circuitry. In 1993 he became assistant director of the Quantum Electron Device Laboratory at Fujitsu Laboratories Ltd. in Atsugi, Japan, where he led research on nanoelectronics. He was on the faculty of Stanford University as acting professor of Electrical Engineering from 1996 to 1999, and he is currently the Louis J. Schnell Professor of Electrical & Computer Engineering at the University of Minnesota. He served as associate editor of IEEE Electron Device Letters and was co-editor of the book ?High Speed Heterostructure Devices? of the Academic Press Semiconductor and Semimetals Series. Professor Kiehl is a member of the American Physical Society and the American Chemical Society, and a Fellow of the Institute for Electrical and Electronics Engineers.
