The characterization of p-GaAs/i-InGaAsN/n-GaAs hetero-junction solar cell with various DMHy flow rates

Wu T.H., National Cheng Kung University, TW

Since the high efficiency tandem solar cell sturcture has been reported, the conversion efficiency of triple-junction solar cells would achieve 40% with concentrator. To further enhance the conversion efficiency of solar cells, the fourth-junction is [...]

Overcome the Doxorubicin Resistance by Multimodal Nanoparticles in Mice

Lai P.S., Hsu C.Y., Lu H.-L., Yu H.-P., Syu W.-J., Shieh M.J., National Chung Hsing University, TW

The efficacy of many chemotherapeutic agents is reduced in cells that have developed multiple drug resistance (MDR). To address this important problem, a biodegradable polymer was coupled to the photosensitizer and the resulting photosensitizer-nanoparticles were [...]

Enhanced Cell Electro-permeabilisation Combined with Phototherapy to Target-Killing Cancer Cells by Using Multi Functional Carbon Nanotubes

Lee P-C, National Taiwan University, TW

Carbon nanotubes (CNTs) have been proposed and actively explored as multifunctional innovative carriers for drug delivery. This project presents a new modality for cell electro-permeabilisation based on the use of CNTs and external static electric [...]

Synthesis, Characterization and Antibacterial Activity of Glycol Chitosan Modified Superparamagnetic Nanoparticles

Chen B.H., Inbaraj B.S., Fu Jen University, TW

Superparamagnetic iron oxide nanoparticles (IONPs) are particularly attractive as antibacterial agents owing to their precise bacterial biofilm and cell targeting in vivo achieved by magnetic driving. In this work, superparamagnetic IONPs modified with water-soluble glycol [...]

siRNA and Paclitaxel Loaded PEG-PCL-PEI Tri-block Polymeric Micelle for Gene and Chemo-therapy Applications in Multidrug-resistance cancer cell

Hsu C.Y., National Chung Hsing University, TW

An annoying problem of chemotherapy was the drug resistance of cancer cell which was expression of multidrug-resistance associated proteins and resulted in ineffective treatment. To conquer this problem, a small interfering RNA (siRNA) molecule and [...]

Vitamin E-assisted Superparamagnetic Iron Oxide Clusters Formation for Magnetic Resonance Imaging

Lai J-R, Lai P.S., Yen H-C, Hsu C.Y., Lai J-R, Lai P.S., National Chung Hsing University, TW

Magnetic Resonance Imaging (MRI) has been regard as a noninvasive powerful imaging tool that yields excellent soft-tissue contrast, has a high spatial resolution, and possesses tomographic capabilities. Among the contrast agents used for MRI, superparamagnetic [...]

Fabrication of PEG Hydrogel Microstructures in Microfluidic System for Multicellular Spheroid Formation, Culturing and Analysis

Fu C.-Y., Chang H.-Y., National Tsing Hua University, TW

In this abstract, we describe a novel PEG-based, simple-to-fabricate, U-shaped micro-scale growth chamber, which allows cell trapping and forming into spheroids as well as culturing in the presence of a continuous perfusion flow, a long-term [...]

Surface Plasmon Grating Coupled Emission from Organic Emitter for Detecting Refractive Index Variation

Chiu N.-F., Lee J-H., Lin C-W, National Taiwan Normal University, TW

We demonstrated the surface plasmon grating coupled emission (SPGCE) from photo-excited organic layer covered with metal thin film on the corrugated substrate. Directional emissions corresponded to the resonant condition of surface plasmon modes on the [...]

Experimental study of sensitivity enhancement in SPR biosensors by use of zinc oxide intermediary layers

Chiu N.-F., Singh A., Nelson-Fitzpatrick N., Dutt S., Evoy S., Lin C-W, National Taiwan Normal University, TW

We report a novel design for the intermediary layer of surface plasmon resonance (SPR) devices that use high refractive index and high-transmittance zinc oxide (ZnO) dielectric layers to enhance the signal quality and improve the [...]

Thin film-resistive gas sensor with SnO2/Au nanocomposite for hydrogen sulfide detection

Chang B-W, Ding S-J, Chen R.L.C., Hungkuang University, TW

A highly sensitive and selective H2S gas sensor has been developed by deposited a SnO2 thin film on an alumina substrate with a spin-coated method. This SnO2 sensing film was be made by a sol-gel [...]
