Toshiyuki AKISHIBA, student at Tabata Laboratory, received the “Outstanding Paper Awards” at the IEEE MEMS 2013 Conference in Taipei, Taiwan, with his paper “DNA ORIGAMI ASSEMBLY ON PATTERNED SILICON BY AFM BASED LITHOGRAPHY”
The conference contribution presents a new integration technique of DNA origami as an excellent platform to arrange various nanomaterials such as metallic nanoparticles, carbon nanotubes and proteins and so on with nanometer scale resolution into MEMS utilizing DNA hybridization of a complementary pair of ssDNAs was demonstrated. A contact-mode AFM based lithography was adopted to form ssDNA modified patterns into an organic thin film with 30 nm resolution on a silicon substrate. A newly designed DNA origami with ssDNA as sticky ends was successfully fixed at specific positions of the substrate by DNA hybridization.
