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 [...]

Ultrasensitive Protein Detection Using an Au/ZnO SPR-Based Biosensor

Chang C-C, Lin C-W, Lin S-H, Chiu N.-F., Lin C-W, Lin S-H, National Taiwan University, TW

In this study, we demonstrated that the Au/ZnO nanocomposite films could be effectively used to enhance the performance of SPR for the detection of tumor marker. Carbohydrate antigen 15.3 (CA15.3) tumor marker for breast cancer [...]

The effect of polymerization rate on the formation of polyaniline nanofibers

Huang Y-F, Lin C-W, National Yunlin University of Science and Technology, TW

This study reports the synthesis of polyaniline (PANI) nanofibers with an average diameter of 30~50 nm using HCl as a dopant. Experiments controlled the polymerization rate in terms of temperature and oxidant concentration. Transmission electron [...]

Optical Characterization of the Au Nanoparticle Monolayer on Silicon Wafer

Wang D-S, Chuang L., Lin C-W, National Taiwan University, TW

In recent years, self-assembly technique has been widely used in fabricating Au nanoparticle layer. It has drawn a lot of attentions owing to its promising application in biosensing.However, to date there have been very few [...]
