Phosphorylcholine-protected Nanoparticles Functionalized with Both Magnetic and Photoluminescent Properties

Chung Y-C, Chen C-J., National University of Kaohsiung, TW

We prepared the magnetite core coated with nano-graded ZnS shell to display superparamagnetic and photoluminescent properties. By adsorbing the phosphorylcholine-ended thiol to stabilize the core-shell nanoparticles, the particles can be well-dispersed in aqueous buffer solution [...]

Regular Nano-Pores Fabricated By UV Cross-Linking Non-softbaked SU-8 Resist In a Solvent Evaporation Controlled Environment

Chang C-J, Tseng F-G, Yang C-S, National Tsing Hua University, TW

This paper proposes a novel technology to fabricate 3D nano pore structures in SU-8 resist, a widely employed resist in MEMS and Bio-chips. Controlling the evaporation rate in SU-8 fabrication process, regular porous structures with [...]

Studies on the Subcellular Trafficking of PAMAM Dendrimer

Lai P.S., Shieh M.J., Pai C.L., Wang C.Y., Lou P.J., National Taiwan University, TW

Polyamidoamine (PAMAM) dendrimers are a new class of highly branched spherical polymers and have emerged as a novel synthetic drug and gene carrier. However, the fate of the dendrimer-nucleotide complexes in a biological environment and [...]

Nano-Structured Vaccine Delivery

Yang Y-W, Wu C-A, National Taiwan University, TW

The nano-structured vaccine delivery systems, containing tomatine, n-octyl-b-D-glucopyranoside (OGP), phosphatidylethanolamine (PE), cholesterol, and ovalbumin, were examined in the present study by transmission electron microscopy. This adjuvant has been shown to elicit cytoxic T-lymphocyte (CTL) effect [...]

Plasma-Treated and Collagen-Coated PLLA Nanofiber Membrane for Cartilage Tissue Engineering

Chen J.P., Lee S.F., Chiang I.P., Chang Gung University, TW

Biodegradable nanofiber membranes from poly-L-lactic acid (PLLA) were prepared by electrospinning to be used as a scaffold in cartilage tissue engineering. Parameters during the electrospinning process were studied in detail in terms of diameters of [...]

Microcap Selective Packaging through Flip Chip Alignment

Chao C.H., Pan C.T., National Sun Yat-Sen University, TW

In this study, the technique of microcap selective bonding for 3-D microstructures using MEMS processes was presented. The flip-chip assembly was successfully demonstrated that the microcap transferred on the selective area of the host substrate [...]

Self-assembled Alternating Nano-scaled Layers

Wu W-Y, Ting J-M, National Cheng Kung University, TW

This paper reports the use of a conventional sputter deposition technique to produce self-assembled alternating nano-scaled layers consisting of diamond-like carbon (DLC) and metal. A conventional sputter deposition technique produces alternating layers only when multiple [...]

Desorption of Surfactant and Sintering of Surface Modified PdxNi1-x Nanoparticles

Wang K-W, Chung S-R, Hung W-H, Perng T.P., National Tsing Hua University, TW

A series of PdxNi1-x nanoparticles in a diameter of 10 nm were prepared by wet chemical reduction. The surface was modified with 1 wt% stearic acid (SA) or polyethylene glycol (PEG). Desorption of the surfactant [...]

Electrochemical Storage of Hydrogen in Carbon Nanotubes

Chung S-R, Wang K-W, Perng T.P., National Tsing Hua University, TW

The electrochemical hydrogenation property of carbon nanotubes (CNTs) was investigated. A slurry consisting of CNTs and a binder was pasted on a Ni foam to form an electrode. The discharge capacity was tested in an [...]
