Chung-Han WANG Cytolysis of HepG2 Induced by Femtosecond Laser
Chung-Han WANG,

Process of cytolysis observed in laser treated HepG2 was analyzed by three-dimensional time-lapse imaging. Transgenic HepG2 cells expressing EGFP and YFP in cytosol and plasma membrane revealed increase of membrane permeability and generation of vesicles having plasma membrane and cytosol were generated from the laser treated cell.

Jie Wang Using optical tweezers to study the effect on collagen type I viscosity caused by thermal denaturation with varying pH and additives
Jie Wang,

In this experiment, we utilized a home-made optical tweezers system to study the effect on collagen Type I viscosity caused by thermal denaturation with varying pH and additives (i.e. glycerol, urea, glucose, and NaCl). Viscosity of collagen samples were determined by measuring the thermal motion of the trapped microsphere by optical tweezers.

Yaping Zhang Investigation of Detection Sensitivity of Silicon Wire Biosensors
Yaping Zhang,Qinyang Sun,

Silicon wire biosensors’ detection sensitivities with TE and TM modes for typical test solutions have been investigated. It was found that the detection sensitivity of TM mode is about 7 times of that of a TE mode. Silicon wires’ detection sensitivities are a few thousand times of that of SOI rib waveguides’.

Ying-Shuo Chiu Ion-sensitive field-effect-transistor-based AlGaN/GaN urea biosensors with gate recessed region using photoelectrochemical method
Ying-Shuo Chiu,Ching-Ting Lee,

The ion-sensitive field-effect-transistor-based urea biosensors were fabricated using the AlGaN/GaN heterostructure. To enhance the sensing performance, the photoelectrochemical etching and oxidation method were applied to recess the gate region and directly grow the sensing membrane, respectively. The sensing sensitivity achieved 17.5 mA/decade within the urea concentration from 0.015M to 50M.

Hsiang-Wei Hsiao In-line fiber hydrogen peroxide sensor based on multimode fiber interferometer
Hsiang-Wei Hsiao,

We proposed an in-line fiber sensor to measure H2O2 concentration with multimode-fiber interferometer. The novel fiber sensor with a no-core fiber (NCF) immobilized peroxidase enzyme (POD) on surface. POD will catalyze H2O2 and lead interference wavelength shifting. The unknown H2O2 concentration sample can be obtained by the wavelength shifting signal.

Hao-Cheng Gao Dispersion changes the spectral shape of third harmonic generation
Hao-Cheng Gao,Alexandra Bausch,Chien-Ming Lee,Chi-Kuang Sun,

Previous study usually believes that dependency between THG spectra and dispersion is negligible. In this letter, we show that dispersions play roles in changing the THG spectral shapes, and this effect should not be neglected for deep tissue THG spectroscopy and microscopy.

Wen-Ling Lin Nanosecond-resolved Fluorescence Anisotropy Measurements on IgG Aggregation
Wen-Ling Lin,Yi-Chun Chen,

We developed a frequency-domain nanosecond-resolved fluorescence anisotropy detection system, which utilized homodyning method to record the fast dynamic fluorescence signals. We applied this technique to study immunoglobulin G (IgG) aggregation level. With our system, we were able to identify difference size of IgG aggregate from time-resolved anisotropy data.

Liang-Yu Chen Comparison of CW and FD Diffuse Optical Imaging
Liang-Yu Chen,Jhao-Min Yu,Min-Chun Pan,Sheng-Yih Sun,Chia-Cheng Chou,Min-Cheng Pan,

The study aims to illustrate that both absorption and scattering optical coefficients images of breast can be reconstructed by only continuous-wave data reliably within a certain extent. Reconstructed images for phantoms with designated absorption / scattering properties of inclusion and background are presented to demonstrate this perspective.

Jia Shiuan Wu Electric field enhancements around a pair of nanorod on a substrate
Jia Shiuan Wu,Yuh-Sien Sun,Gung-Jing He,Yuan-Fong Chau,

Electric field distributions of a pair of silver nanorod on a substrate are performed by the finite element method. We find the incident waves are reflected back by the substrate and the superposition of the electric fields of the incident wave and the reflection wave.

Chun-Hui Yu A Fully Digital Stimulated Emission Microscopy System
Shen ShouMax Chung,Chun-Hui Yu,Fu-Jen Kao,

Stimulated Emission (SE) has distinctive characteristics different from fluorescence lifetime image microscopy (FLIM) in that the coherence nature of SE signals enables long distance observation. In SE microscopy, the coincidences of pump and probe beams in space and time are essential. Previously the coincidence in time was accomplished by translational stage and delay cables, now we can accomplish this by a fully digital system, in which the relative delay between pump and probe beam is controlled by a function generator and delay generator, and delay can be adjusted as short as 30ps.
