Yi-Lun Chiang Protein quantitation based on optical absorption of dye-doped liquid crystal
Yi-Lun Chiang;Mon-Juan Lee;Wei Lee

We developed a biosensing method using a dye-doped liquid crystal. The working system was demonstrated with a black dichroic dye possessing high dichroic ratio for promoting the sensitivity in detecting biomolecules. A polarizer used to make incident light linearly polarized enhanced the resolving power of the detection system.

Ching-Min Lin Protein detection and quantitation based on dielectric responses of dual-frequency liquid crystal
Ching-Min Lin;Po-Chang Wu;Mon-Juan Lee;Wei Lee

This research exploited dielectric properties of dual-frequency liquid crystal (DFLC) to demonstrate its capability of quantitative protein detection. The proposed DFLC-based biosensing can eliminate experimental errors caused by variation in cell gap. Linear correlation between the protein concentration and dielectric responses at designated frequencies was obtained by dielectric spectroscopy.

Kuang-Li Lee Tailoring the Evanescent Field Decay Lengths of Surface Plasmon Resonances Using Alumina-Coated Aluminum Nanoslits
Kuang-Li Lee;Po-Cheng Tsai;Meng-Lin You;Ming-Yang Pan;Pei-Kuen Wei

We propose the combination of capped aluminum nanoslits and a thin nanodielectric top layer to improve the surface sensitivities of nanostructure-based aluminum sensors. We find that the passivation layer can enhance the wavelength sensitivities of the asymmetric Fano resonance in capped aluminum nanoslits by a factor of 3.5.

Yung-Tsan Chen Photonic Crystal Biosensor for Epstein–Barr Virus Protein Detection
Yung-Tsan Chen;Yu-Yang Liao;Jian-Jang Huang

A 2-D photonic crystal biosensor with cost-effective measurement system was developed in this study. By analyzing the spectra of the diffraction beam,and using Epstein–Barr nuclear antigen-1 (EBNA-1) antibody as analyte, the biosensor is able to detect 10 ng/mL of EBNA-1 antibody in the phosphate buffered saline (PBS) solution.

Ting-Ying Li Development of a neurofeedback training system based on wearable NIRS device to improve attentional capability in children with Tourette syndrome
Ting-Ying Li;Pou-Leng Cheong;Chia-Wei Sun

NIRS neurofeedback training serves as a physical therapy for Tourette syndrome children not only to decrease the drug side effect but to improve SNR in comparison to EEG. We built a neurofeedback system including a training software and a wearable NIRS device with 4 channel covering prefrontal area.

Jia-Hao Li Simulation analysis of the transmittance of Cornea and Sclera
Jia-Hao Li;Snow H. Tseng

Cornea and Sclera both consist of collagen fibrils, but the optical characteristics aren’t the same. Using the pseudospectral time-domain (PSTD) simulation technique, changing different sizes and arrangements of the non-absorbing collagen fibrils and analyzing the scattering characteristics of light of the cornea and sclera.
