Surfactant concentration modulates the motion and placement of microparticles in an inhomogeneous electric field
Marcos Masukawa, Masayuki Hayakawa, Masahiro Takinoue
This study examined the effects of surfactants on the motion and positioning of microparticles in an inhomogeneous electric field. The microparticles were suspended in oil with a s…
Collective ratchet transport generated by particle crowding under asymmetric sawtooth-shaped static potential
Masayuki Hayakawa, Yusuke Kishino, Masahiro Takinoue
In this study, we describe the ratchet transport of particles under static asymmetric potential with periodicity. Ratchet transport has garnered considerable attention due to its p…
Sequence design-based control of DNA droplets formed from phase separation of DNA nanostructures
Yusuke Sato, Tetsuro Sakamoto, Masahiro Takinoue
DNA has the potential to realize a controllable liquid-liquid phase separation (LLPS) system, because the design of its base sequences results in programmable interactions. Here, w…
Mode bifurcation on the rythmic motion of a micro-droplet under stationary DC electric field
Tomo Kurimura, Masahiro Takinoue, Masatoshi Ichikawa +1
Accompanied by the development of microfabrication techniques, such as MEMS and micro-TAS, there has been increasing interests on the methodology to generate a desired motion on a…
