DNA nanostructure
The double stranded DNA model was created for production of DNA nanostructure applied DNA origami technology. The model with electrostatic interaction was discussed. We confirmed that the dependency of the salt concentration on the persistence length of the nCG-dsDNA model at the 30% charge is in good agreement with the Poisson–Boltzmann theoretical model.
Laser microfabrication process
Laser microfabrication of goid nanoparticles dispersed polymer film is prposed. Since wave length of laser beam is selected an absorption wavelength by plasmon resonance vibration of gold nanoparticles, the polymer film can be micromachined. In this study, we focus the effect of size and distribution of naoparticle on laser processed shape.
Microfluidic device
A glass microfluidic device with mcirochannel is fabricated by micropowder blasting, and the prepareation of metalic nanoparticles on the produced device is prposed. In this study, we focus the production of device which can synthesize nanoparticles by liquid-phase reduction method.
Simulation of polymer resist for MEMS
The mechanical property of the polymer resist is required for development of MEMS microfluidic device. We predict the relationship between the mechanical property and the structure of resist in molecular scale by coarse grained molecular dynamics simulation.
Simulation of rubber materials
A polymer chain is treated as a simple beads-spring model, and the viscoelastic and elongation behavier of the model is simulated using molecular dynamics calculation software such as OCTA/COGNAC and LAMMPS with supercomputer according to the model scale.
Simulation of micropowder btasting
We predict processed shape on a glass substrate by powder btasting using cellular automaton method. The simulator is improved by comparison of experimental result and simulated result, in addition of the production of processing system.
