Chao-You Hung Write-Read-Erase DNA Biopolymer Memory Devices
Yi-Tzu Lin,Waan-Ting Tu,Chao-You Hung,Yu-Chueh Hung,

Deoxyribonucleic acid (DNA) biopolymer material has been attracting great interest for years and became a promising material for many optoelectronic applications. In this study, we reported the fabrication of the DNA biopolymer with silver nanoparticles using a photochemical method and demonstrated a device performing a write-read-erase memory characteristic.

Yi-Chang Wu Intracellular Stiffness of Different Epithelial-Mesenchymal Transition Phenotypes Studied by Video Particle-Tracking Microrheology
Yi-Chang Wu,Arthur Chiou,

Epithelial–mesenchymal transition (EMT), a crucial process in tumor metastasis, is often associated with the reorganization and restructuring of actin cytoskeletons, resulting in a change in intracellular stiffness. We measured the intracellular stiffness at different stages of EMT for potential application in the evaluation of metastatic potential of cancer cells.

Cheng Nai-Lun Portable LED Induced Autofluorescence (LIAF) imager for Oral Cancer Diagnosis by RGB ratio
Cheng Nai-Lun,Tsai Ming-Hsui,Chiou Jin-Chern,Duann Jeng-Ren,Lin Yung-Jiun,Huang Ting-Wei,Yang Chin-Siang,Li Sing-Tsung,Liu Ying,Ou-Yang Mang,Hsieh Yao-Fang,

We developed a portable LED induced autofluorescence (LIAF) imager through 365nm and 472nm wavelength as excitation light sources to capture ex-vivo oral tissue autofluorescence image. The device achieves a sensitivity of 87.26% and specificity of 62.90% when using normalized blue-to-green ratio analysis method on autofluorescence image with 365nm excitation light source.

Ting-Yen Tsai Evaluation of fractional laser-assisted drug delivery with optical coherence tomography
Ting-Yen Tsai,Chih-Hsun Yang,Su-Chin Shen,Chau Yee Ng,Shih-Ming Jung,Meng-Tsan Tsai,

To ensure proper energy delivery without damaging tissue structures beneath the nail plate, optical coherence tomography (OCT) was implemented for quantitative evaluation of induced microscopic ablation zone (MAZ). To further study the feasibility of drug delivery, normal saline was dripped on the exposure area of fingernail and the speckle variance in OCT signal was used to observe water diffusion through the ablative channels into the nail plate.
