DNA Detection Using Metal-Fluorescence Interactions on Two-Dimensionally Assembled Gold Nanoparticles

Nakahara M., Taniguchi S., Inoue T., Hitachi Ltd., JP

We developed a novel DNA detection system using a single stranded probe oligonucleotide with a fluorophore immobilized on two-dimensionally assembled gold nanoparticles. This system enables the detection of amplified DNAs without fluorescence labeling. In the [...]

Three-Dimensional Effects Obtained from Capacitance Analysis of an SRAM Cell

Takemura Y., Osada K., Yagyu M., Yamaguchi K., Ushio J., Maruizumi T., Hitachi Ltd., JP

Employing Green's function method, we analyzed the 3D capacitance for the hole interconnect structure in an SRAM cell. We found novel 3D effects as follows; (1) via connection increases the capacitance of parallel lines, (2) [...]
