How can we improve functionality of MEMS by incorporate nanoscale structure made of various nanomaterials such as nanoparticles, nanotubes, proteins and other molecules? One promising way is to utilize self-assembly technique of multiple functional nanocomponents as nature does. Although a complexity of the structure is an essential factor to generate functionality, so far, no engineering methodology has been realized to assemble multiple functional nanocomponents to specific positions on MEMS in a specific sequence. It is a challenging goal to be addressed thatcontrolling assembly position and sequence of multiple nanoscale functional components , which is made of a variety of nanomaterials, realize high functional nanosystem.

To address this goal, a concept of an Oriented Self-Assembly on MEMS (OSAM) approach in which DNA is utilized to bridge MEMS and nanotechnology has been proposed. In this approach, DNA origami (DO) proposed by Rothemund in 2006 is self-assembled on MEMS according to a given system design. The advantages of DO as a nanocomponent can be summarized as: (1) the surface is precisely addressable with sub-nanometer resolution, (2) various nanomaterials can conjugate with DO, (3) higher order structure (multimer structure) can be formed by binding them each other, (4) various 2D or 3D shape can be constructed, (5) mechanical rigidity is controllable, (6) DNA based sensing and actuation mechanism can be incorporated. Owing to these advantages, many applications including nano-plasmonic structures for sensing, drug delivery system will be expected. In this talk, the current status of DNA nanotechnology, OSAM and related topics will be presented.
