Chia-Lun Tsai Award Candidate Characterization of two photon excitation from Red-activatable Channelrhodopsin

We have experimentally characterized two photon excitation effect on red-activatable Channelrhodopsin (ReaChR) by a wavelength tunable 3-stage optical parametric amplifier. In our results, optimal central wavelength is at 1250 nm and intensity is at 13.9 GW/cm2 to trigger Crz neuron which can behave abdomen bending behavior.

Kuei-Hung Chuang Award Candidate Gender-Related Effect in Oxygenation Dynamics by Using Far-infrared Intervention with Near-infrared Spectroscopy Measurement

Many studies have indicated the microcirculation can directly respond to disease-related symptoms. However, the capacity of microcirculation would vary due to the gender differences. Near-infrared spectroscopy (NIRS) is a noninvasive technique to monitor tissue oxygenation dynamics. In this study, the far-infrared (FIR) source was used for physiological intervention of microcirculation.

Ying-Kai Liao Silicon-based Horizontal Surface Plasmon Interferometer for Biosensing

For simple yet robust processing of on-chip integrated plasmonic waveguides, the metal coated on all sides of silicon-wire was utilized to form the horizontal surface plasmon interference biosensor coupled with TE-polarized input/output grating structures. The sensitivity demonstrated 511-nm per refractive-index-unit, which was 10% improvement compared with TM-polarized top-metal interference sensing.

Nicholas Smith Targeted Intracellular Surface-enhanced Raman Measurements

Intracellular gold nanoparticles allow the Raman measurement of molecular conditions during cellular reactions. However, with no control over spatial locations, quantitative mapping is difficult. This presentation shows 2 methods to help quantify or control the relations between nanoparticle location and resulting surface-enhanced Raman signals in biological cells.

Chong Ming Shao The study on localized surface plasmon resonance for 2×2 nano-cylinder metal-particle array

In this study, we performed parameters analysis of the structure of a 2 × 2 nanocylinder metallic array, including the gap between nanoparticles and the refractive index of the analyte. The results indicate that the energy of the stimulated localized surface plasmon resonance was the greatest when the gap was 106.5 nm and the refractive index of the analyte was 1.33.

Shang Ruei You Use Real Time Polarization Optical Coherence Tomography to Detect Dental Calculus

Polarization-sensitive optical coherence tomo-graphy (PS-OCT) has been designed for clinical studies in the segment imaging of the eye because of light polarization and birefringence structure; likewise, the teeth also have the same properties. In this paper, we display a simple way about phase retardation to distinguish dental calculus with the healthy segments of the teeth

Yu-Hsiang Su In Vivo Quantification of Melanin Distribution in Melasma Patients by Using Third Harmonic Generation Microscopy

To better assess the treatments to melasma and to eke out its cure, dermatologists desire the information of melanin distribution in skin. We propose a method using harmonic generation microscopy (HGM) to quantify the melanin distribution and obtain a mean mass melanin density of 16.7 mg/ml in epidermis of malasma.

Hong-Cing Wu Liquid Crystal Sensor for Label-free Monitoring enzyme solution

A liquid crystal (LC) biosensor for label-free identification of enzyme aqueous solutions is presented. The biosensor is achieved mainly by using gold–nanoparticles (GNPs) and LC film. As the reaction layer GNPs are reacted with the enzyme, the alignment of LCs will be disturbed, and then the color and brightness of LC-sensing device are changed. By analyzing the brightness transition caused by the reaction between the GNPs and enzyme solutions the relationship between enzyme concentration and reaction time can be established.

Yu-Yen Wang Full-field optical coherence tomography for skin tissue imaging

Full-field optical coherence tomography (FF-OCT) is suitable for rapid en-face imaging, since it used a 2D imaging device for planar interference and pixel processing. In this research, the images of different skin tissue layers were obtained from the system. The results showed both high resolution and penetration depth by using LED source in FF-OCT system. Noninvasive skin tissue imaging contributes to advance dermatology and cosmetology.

Pei-Ju Chiu Fluorescence of the scorpion cuticle

The fluorescence of scorpions under UV light is a well-known phenomenon. This interesting phenomenon was first reported in 1954[1-5]. But to date, there is no clearly conclusion has been reached of the mechanism. Another interesting phenomenon is that the scorpions are nocturnal and avoid sunlight, so the reason of the fluorescence is also a mystery of scorpions.

Bo-Wen Wang Fluorescence of dental plaque under specific excitation light

Dental plaque emits fluorescence when it is excited by the Ultraviolet (UV) light. There were some products with different wavelength of excitation light, however, they can't recognize dental plaque from the fluorescence image very well. Finding what wavelength of excitation light would emit the significant fluorescence is of benefit for the detection of dental plaque.

We proposed a method to increase the surface sensitivities of caped silver nanoslit biosensors. Under oblique angle incidence, the coupling of a cavity mode to the split Bloch wave surface plasmon polariton mode generates an asymmetric Fano resonance. Compared to normal incidence, the surface sensitivity of the coupled mode is improved by 2.5 times.
