Journal ArticleDOI
Micrometer-sized molecular robot changes its shape in response to signal molecules
TL;DR: An amoeba-like molecular robot is constructed that can express continuous shape change in response to specific signal molecules and the results show that the components of the robot were consistently integrated into a functional system.
Journal ArticleDOI
DNA cytoskeleton for stabilizing artificial cells
Chikako Kurokawa,Kei Fujiwara,Masamune Morita,Ibuki Kawamata,Yui Kawagishi,Atsushi Sakai,Yoshihiro Murayama,Shin Ichiro M. Nomura,Satoshi Murata,Masahiro Takinoue,Miho Yanagisawa +10 more
TL;DR: Results clearly show the DNA gel shell is a stabilizer of the lipid membrane akin to the cytoskeleton in live cells, and it is demonstrated that liposomes with theDNA gel shell are substantially tolerant against outer osmotic shock.
Journal ArticleDOI
Supramolecular 1-D polymerization of DNA origami through a dynamic process at the 2-dimensionally confined air–water interface
Yusuke Yonamine,Yusuke Yonamine,Keitel Cervantes-Salguero,Kosuke Minami,Ibuki Kawamata,Waka Nakanishi,Jonathan P. Hill,Satoshi Murata,Katsuhiko Ariga +8 more
TL;DR: A Langmuir-Blodgett (LB) system has been utilized for the regulation of polymerization of a DNA origami structure at the air-water interface as a two-dimensionally confined medium, which enables dynamic condensation of DNA Origami units through variation of the film area at the macroscopic level.
Journal ArticleDOI
Reversible Gel-Sol Transition of a Photo-Responsive DNA Gel
Daisuke Kandatsu,Keitel Cervantes-Salguero,Ibuki Kawamata,Shogo Hamada,Shin Ichiro M. Nomura,Kenzo Fujimoto,Satoshi Murata +6 more
TL;DR: An X‐shaped DNA motif that turns into a gel by hybridization of self‐complementary sticky ends is proposed by embedding a photo‐crosslinking artificial base in the sticky‐end sequence and repetitive gel–sol transitions are achieved through UV irradiation at different wavelengths.
Journal ArticleDOI
Large Deformation of a DNA-Origami Nanoarm Induced by the Cumulative Actuation of Tension-Adjustable Modules
TL;DR: The adjustability and scalability of the DNA origami nanoarm provide a versatile design of DNA nanodevices that exhibit large deformation in response to external stimuli.
