Hyperhtermia effect of surface-modified magnetite nanoparticles in a microfluid system

Lin C.Y., Ho K.C., National Taiwan University, TW

Fe3O4 nanoparticles (NPs) was first synthesized via coprecipiatation. After synthesis and purification of the Fe3O4 NPs, poly(acrylic acid) (PAA) was coated on them at specified conditions. The coating process is not possible at pH higher [...]

Synthesis of superparamagnetic magnetite nanoparticles for thermoresponsive drug delivery

Lin C.Y., Ho K.C., National Taiwan University, TW

Superparamagnetic magnetite nanoparticles (MNPs) were synthesized via modified coprecipitation method and their physical properties were examined. The crystal structure of Fe3O4 nanoparticles (NPs) was confirmed by X-ray diffraction. From the dynamic laser scattering analysis, the [...]

Controllable synthesis of patterned ZnO nanostructures based on the templation of plant cell walls

Chang Y-T., Tung I-C, Chen C-Y, Chen C.C., Tsai M-W, Chan C-H, Chang Y-T., Chen C-Y, Chen C.C., Lee S-C, National Taiwan University, TW

Extraordinary transmission through Al/Si structure perforated with random distribution of holes. The (1, 0) Al/Si surface plasmon mode due to hole array with 1st nearest neighbor distance. The transmission peak intensity is found to depend [...]

Optimization of Piezoelectric Transformers Using Elite Genetic Algorithm

Kang C-Y., Lee C-K, Yang Y-J, National Taiwan University, TW

In this work, we present the optimization work for piezoelectric transformers (PT) by using the elite Genetic Algorithm (GA). The Finite-element solver, NTUPZE, is used to calculate the behaviors of piezoelectric transformers. The design parameters [...]

Transmission Spectrum of PDMS in 4-7µm Mid-IR Range for Characterization of Protein Structure

Chen K-C, Chen Y.F., Wo A.M., Chen K-C, Chen Y.F., National Taiwan University, TW

Infrared (IR) spectroscopy has been an important tool to characterize secondary structure of proteins for decades. To extend PDMS-based micro-device into spectroscopic characterization of proteins for structural study, the transmission spectrum of PDMS over the [...]

Macromodeling for Microfluidic Channels

Kuo C-W, Chein C-M, Yang Y-J, National Taiwan University, TW

In this paper, we present a methodology of generating microfluidic macromodels (reduced-order models) for 3-D non-linear microchannels. Compared with the full-meshed simulations, the generated macromodels not only provide accuracy results, but also give three-orders-of-magnitude speed-ups. [...]

Synthesis and Photodynamic Efficacy of PAMAM-Photosensitiser Conjugates in Vitro

Peng C.L., Lai P.S., Lai T.-Y., Chiu C.H., Chang C-C, Lai P.S., Lai T.-Y., Shieh M.J., National Taiwan University, TW

Starburst polyamidoamine (PAMAM) dendrimer is a new class of highly branched spherical polymer. Covalent attachment of porphyrin to PAMAM dendrimer may alter the pharmacokinetics, cell targeting, and photophysical properties of photosensitizer. We investigated the uptake, [...]

Shell Cross-Linked Nanoparticle Based on Poly(e-caprolactone)-Poly(ethylene glycol) for Photosensitizer Delivery

Lai P.S., Huang M.Y., Wang S.J.J., Chen C.N., Shieh M.J., National Taiwan University, TW

Photodynamic therapy (PDT) is a novel photochemical process for producing localized tissue necrosis, which involves the activation of a photosensitizing drug in the target tissue with light of a specific wavelength matched to an absorption [...]

Application of nanoparticle in photodynamic diagnosis for colorectal cancer

Yang S.J., Peng C.L., Lai P.S., Lin F.H., Shieh M.J., National Taiwan University, TW

Photodynamic medicine is a novel approach for cancer therapy and diagonosis via different photosensitizers and suitable light source. The 5-Aminolevulinic acid (5-ALA) can be converted into protoporphyrin IX (Pp IX ) that can be utilized [...]
