Effect of Substratum Morphology on Cell Behavior

Su W-T, Chu I-M, Yang J-Y, Lin C-D, National Nano Device Laboratories, TW

Contact guidance induced by the surface topography of the substrata influences the direction of cells with artificial material. Mouse bone marrow stromal fibroblast was examined on grooved substrata of varying dimension (0.3£gm~1.2£gm groove width, 0.5£gm [...]

An Chip-based-Instant Protein Micro Array Formation and Detection System

Tseng F-G, Ho C.E., Chen M.H., Chen Y.F., Hung K.Y., Su C-J, Chen M.H., Chen Y.F., Huang H.M., Chieng C-C, National Tsing Hua University, TW

This paper proposes a novel protein micro arrayer employing 3-in-1 chip system, instantly delivering hundreds of biosamples in parallel for disease diagnosis. The 3-in-1chip system included: micro filling chip, micro stamper array and micro bio-reaction [...]

The Structures of Fibril Aggregates of Beta-amyloid Peptide 1-40 upon Addition of Dihexanoylphosphatidylcholine

Lin C-M, Lin H-N, Lin T., Huang C-L, Lin C-M, Lin H-N, Lin T., Lin C-M, Lin H-N, Lin T., National Tsing Hua University, TW

The amyloid peptides were found to form fibril aggregates in aqueous solutions and the formation of fibril aggregates is thought to be the cause of the Alzheimers disease [1-2]. It was found that the beta-amyloid [...]

Excited Electronic States and Production Optimizations for Promising Nano-Agents

Slanina Z., Kobayashi K., Nagase S., Academia Sinica, TW

Very high temperatures of fullerene and nanotube syntheses do allow for a significant population of excited electronic states and thus for non-negligible electronic partition functions. This unique feature can have some interesting consequences for computed [...]

An Improved Single-Electron-Transistor Model for SPICE Application

Wu Y-L, Lin S-T, National Chi-Nan University, TW

Single electron transistors (SETs) have drawn much attention of researchers and scientists because they are considered candidate as one of the elements for future low power, high-density memories and logic circuits. Instead of using Monte [...]

Compositional Inhomogeneity of Pd70Ag30 Alloy Nanoparticles

Wang K-W, Chung S-R, Jang L-Y, Lee J-F, Perng T.P., National Tsing Hua University, TW

The compositional inhomogeneity of Pd70Ag30 nanoparticles with the size of 6-7nm was studied by X-ray absorption near edge structure (XANES). The composition of the as-prepared nanoparticles by chemical reduction is inhomogeneous across the diameter due [...]

Effect of Palladium Size on its Chemical Activity

Huang C-D., Huang S.Y., Huang C-D., Huang S.Y., Chang B-T., Yeh C.T., National Tsing Hua University, TW

Palladium crystallites with size down to d < 1 nm or were successfully dispersed on silica support and characterized with TEM. A process of hydrogen absorption into the dispersed crystallites were studied by a simultaneous [...]

Increase the Synthesis Efficiency of Graphite Encapsulated Cobalt Nanoparticles by Annealing

Teng M.H., Lin C.C., National Taiwan University, TW

Graphite/carbon encapsulated metal (GEM) nanoparticles (Fig.1) not only provides an opportunity to study dimensionally confined systems, but also could be used in many nanotechnology applications, e.g. recording media, nano-sized wheel bearings, etc. Unlike other metal [...]

Effects of Electric Field on the Growth of One-dimensional Carbon Materials in the Chemical Vapor Deposition Process

Tai N-H, Lee C.-Y., Chiu I-C, Lin I-N, National Tsing Hua University, TW

Effects of Electric Field on the Growth of One-dimensional Carbon Materials in the Chemical Vapor Deposition Process (PCVD) Nyan-Hwa Tai* a), Chi-Young Lee b), I-Chang Chiu a), and I-Nan Lin b) a)Department of Materials Science [...]

Self-assembly of Deinococcus Radiodurans S-layer Proteins

Lin J., Tan T.S.T., National Tsing Hua Univ., TW

Proteins capable of self-assembly are crucial to many bio-architectures and have potential applications in nanotechnology. An example is the group of proteins used to construct crystalline surface layers (S-layers) in nearly all archaebacteria and many [...]
