Title: SELECTIVE ASSEMBLY OF DNA NANOSTRUCTURE BRIDGING ONTO A TRENCHED SILICON SUBSTRATE

Abstract
We demonstrated for the first time the versatility of the previously proposed concept of DNA nanostructure integration on MEMS by selectively assembling DNA nanostructures to form a bridge over a trenched silicon. A DNA origami (30 × 150 nm) was fixed to bridge the trench (100 nm width) using the hybridization between ssDNA on the DNA origami and immobilized ssDNA-pattern at the edges of trench. An ODS-SAM was utilized as a masking layer for a SPL with better process stability than a TMS-SAM.

Title: MICROFLUIDIC DEVICE TO INTERCONNECT MULTIPLE ORGANS VIA FLUIDIC CIRCULATION: TOWARDS BODY-ON-A-CHIP

Abstract
We developed a simplified microfluidic device (1) assembling multiple organs within a device and (2) integrating a closed-loop medium circulation system to investigate the effects of drug candidates and their metabolites on two organs, namely body-on-a-chip. For its fabrication, simple and reliable 3D lithography was applied to improve the PDMS molding. The fabricated PDMS microfluidic device was successfully applied to evaluate the effects of an anti-cancer drug (Doxorubicin) on cell survival.

Title: A SUB-MICRON-GAP SOI CAPACITIVE ACCELEROMETER ARRAY UTILIZING SIZE EFFECT

Abstract
We have developed a 10×10 single-axis accelerometer array, whose dimensions are 1/10 of typical accelerometers. Here, the size effect of the capacitive sensitivity is investigated. To solve the pull-in problem, which is more apparent on miniaturizing, nonlinear programming to optimize dimensions is used. The accelerometer is fabricated using electron beam lithography. The fabricated accelerometer was successfully operated without pull-in, which showed our design method was useful to avoid it.
