Nanosystem in which multiple nano-scale functional building blocks made of variety of nano-materials integrated with MEMS becomes increasingly important as a key device for next generation MEMS devices. An assembly technique bridging the gap between nano-scale building blocks and micro-scale MEMS is expected to play an important role as a complementary approach for a top-down and a bottom-up approaches to realize Nanosystem. The author termed a systematic approach to realize Nanosystem using eight unit operations of a self-assembly such as synthesis, transfer, sorting, positioning, alignment, placement, bonding and interconnection as SENS (Synthetic Engineering for Nano System) and started a relevant research intensively [Tabata, ECS Trans., 16, 15, pp.49-64, 2008].
One of the challenging points for the SENS is implementation of a self-assembly sequence control of multiple functional building blocks in a pre-determined order to realize highly functional Nanosystem. As a first step, the author proved the feasibility of the idea to utilize DNA which can be engineered as an intelligent adhesive to assemble micrometer scale silicon components. As a second step, the research project is in progress to use a hundred nanometer scale rectangular DNA origami scaffold as a functional building block on which a simple ordered nano-structure composed of nanomaterial such as nano-particle, carbon nanotube etc are arranged.
All the assembly sequence is carried out at “Nanosystem Assembler” which utilizes a micro fluidicdevice. In this presentation, the detail of the proposed approach and preliminarly experimental results will be presented. Furthermore, the remaining problem to be solved to realize SENS by DNA nanotechnology will be overviewed.
