Kazunori Okano Induction of target cell death and detachment by femtosecond laser


We show that femtosecond laser induces target cell death without damage to surroundings. The target cell started to accumulate trypan blue immediately after laser irradiation, and was finally detached from substrate. Fluorescence lifetime analysis of EGFP-expressed HepG2 cells revealed that cytosolic pH is decreased to around 5.

Min-Chun Pan Ring-scanning Diffuse Optical Imaging System


In this paper, we propose and implement a three-dimensional (3D) ring-scanning equipment for near infrared (NIR) Diffuse optical imaging (DOI) to screening breast tumor under prostrating examination. This equipment has a flexible combination of illumination and detection can be configured for required resolution.

Chen-Wei Chen Usefulness of simultaneous electroencephalography near-infrared spectroscopy in mental focus task for WCST


Coregistration of electroencephalography and near-infrared spectroscopy (EEG-NIRS) was used to analyze the changes in both electrical and local hemodynamic activities of human brain. And, we use the Wisconsin Card Sorting Test (WCST) as mental focus task to get the physiological signals of subjects’ brain. These information can help us to understand subject’s degree of mental concentration.

Yi-Hao Chen Fibroblast Invasion into Cancer Cell Spheroid Revealed by Bessel-Beam Selective Plane Illumination Microscopy


Interactions between cancer cells and stromal cells are recognized as potential therapeutic targets. However, animal studies are expensive and cumbersome. We used Bessel-beam selective plane illumination microscopy (SPIM) to observe the interaction between fibroblast and a cancer-cell spheroid. We found the fibroblast can invade into a preformed cancer-cell spheroid.

Yen-Hung Lin Ti:sapphire crystal fiber based full-field OCT on dermis/epidermis junction measurement


A Ti:sapphire crystal fiber based full-field optical coherence tomography system is demonstrated with lateral and axial resolutions of 1.67 and 1.65 μm, respectively. A depth of 315 μm was characterized in vivo. At forearm, the average depth of rete ridge is 64.11 μm with a standard deviation of 17.8 μm.

CHUN-JUNG HUANG Low-resource portable Diffuse Optical Imaging system


In this paper we have developed a low-resource portable Diffuse Optical Imaging (DOI) system containing 8 laser diode sources and 1 silicon detector on our designed probe. DOI offers the capability to simultaneously quantify the tissue concentration of both oxy- (HbO2) and deoxy-hemoglobin (Hb).We discuss the engineering issues and describe the design and evaluation of the continuous-wave (CW) DOI system.
