Microfreight Delivered by Chemical Waves
Full Text HTML
Hi-Res PDFAbstract
We report the vectorial transport of a material object to a desired location by chemical waves generated in an excitable medium (Belousov−Zhabotinsky reaction). The transportation route is determined by the excitable waves induced at a certain point on the excitable medium. This study realized direct coupling between a chemical reaction and vectorial motion; such transduction of energy is generally found in biological motility but has been difficult to achieve in artificial model systems. We discuss the future possible application of these findings to the fabrication of a chemical machine that works under the self-management of motion in response to external stimuli.

Nobuhiko J. Suematsu, Yumihiko Ikura, Masaharu Nagayama, Hiroyuki Kitahata, Nao Kawagishi, Mai Murakami and Satoshi NakataThe Journal of Physical Chemistry C2010 114 (21), 9876-9882We demonstrated mode-switching of self-motion coupled with diffusion of molecules at a solid/liquid interface. A camphor boat moved spontaneously on water and the mode of self-motion depended on the setup of the boat. When a camphor disk was connected to ...
Self-Motion of a Camphor Disk on an Aqueous Phase Depending on the Alkyl Chain Length of Sulfate Surfactants
Satoshi Nakata and Mai MurakamiLangmuir2010 26 (4), 2414-2417Self-Motion of a Camphor Disk on an Aqueous Phase Depending on the Alkyl Chain Length of Sulfate Surfactants
Satoshi Nakata and Mai MurakamiLangmuir2010 26 (4), 2414-2417A change in the mode of self-motion was investigated for a camphor disk on water upon the addition of sulfate surfactants with alkyl chains of different lengths as a simple autonomous system. With an increase in the concentration of surfactant with a ...
