A synthesis of gold nanoparticles (GNPs) dispersion in an organic solvent by a glass microfluidic device was reported in this paper. Brust-Schiffrin synthesis method can prepare GNPs dispersion in toluene. However, since the method is a complex synthesis process such as mixing and separation, control of nanoparticle size was difficult. A glass microfluidic(More)
New coarse-grained molecular dynamics model of double stranded DNA (nCG-dsDNA model) was reported. The nCG-dsDNA model was made by newly developed simple bead-spring model for realizing a helix structure. The phosphate group, sugar group, and base group in an actual double stranded DNA chain were represented by a single bead. The nCG-dsDNA model with 202(More)
Laser microfabrication technique of a polymer film using absorbance of Au nanoparticles for realizing nano-microstructure was proposed. The polymer films are made of ethylcellulose in which Au nanoparticles was dispersed. Since the absorption spectrum which influences laser processing ability depends on size of Au nanoparticle in polymer, four size of Au(More)
A new coarse-grained molecular dynamics double-stranded DNA model (nCG-dsDNA model) using an improved beads-spring model was proposed. In this model, nucleotide comprising phosphate, sugar, and base group were replaced by a single bead. The double stranded model with 202 base pairs was created to tune the parameters of the bond, the nonbond, stack, angle(More)
