Abstract
DNA nanotechnology provides a way to utilize DNA as an engineering material to construct nano-scale functional building blocks conjugated with variety of nano-materials. In this talk, a new approach based on DNA nanotechnology, Programmable Oriented self-assembly on MEMS (P-OSAM), is introduced as a promising technology to integrate nanostructures with nanomaterials into MEMS to realize nanosystems with new functionality. In this approach, an assembly technique bridging the gap between nano-scale building blocks fabricated by DNA nanotechnology and micro-scale MEMS plays an important role as a complementary approach for a top down and a bottom up approach. It is demonstrated that DNA nanostructures are successfully positioned and fixed by complementary single strand DNA hybridization at a nanoscale pattern on a silicon substrate formed by a scanning probe lithography technique. Furthermore, an on-going research project on the establishment of design and characterization tools for DNA nanostructures is introduced.

Biography
Osamu Tabata was born in 1956. He received the M.S. and Ph.D. degrees from Nagoya Institute of Technology, Nagoya, Japan, in 1981 and in 1993. Since 1981, he had been with the Toyota Central Research and Development Laboratories, Inc., Aichi, Japan. In 1996, he joined the Department of Mechanical Engineering, Ritsumeikan University, Shiga, Japan. In 2003, he joined the Department of Mechanical Engineering, Kyoto University, Kyoto, Japan. Since April 2005, he has been a Professor at the Department of Micro Engineering, Kyoto University, Kyoto, Japan. He was Visiting Professor at Freiburg University in Freiburg, Germany in 2000 and at ETH Zurich, Switzerland in 2001. He was Senior Visiting Fellow of the Chinese Academy of Science in 2010, External Senior Fellows of School of Soft Matter Research, Freiburg Institute for Advanced Studies (FRIAS) at Albert-Ludwigs-Universität Freiburg from 2010, and Guest Professor at Huazong University of Science and Technology from 2011. He is currently engaged in the research of micro/nano processes, MEMS and micro/nano system synthetic engineering. Especially, he is focusing on the research to realize a unique and novel nanosystem by assembling the various functional components such as a microchip, a particle, a microcapsule, DNA origami, a cell, etc., with sizes ranging from the nanometer to micrometer scale on a few mm square MEMS substrate. This technology is termed SENS (synthetic engineering for nano systems), and experimental and theoretical research on the establishment of SENS is pursued.
