摘要

本研究開發一套以手持式移液器(Pipette)與微流道晶片組成的微流式細胞儀(Microflow cytometry)系統，並搭配光纖、光纖雷射、光學濾鏡(Dichroic mirror)、反射光學鏡面及光電倍增管(Photomultiplier tube)整合成光訊號傳遞模組。

微流道晶片採用微量吸管(Tip)熱壓製成，以達到成本低、體積小、方便更換之特性，研究中使用螢光粒子(F8843、UMDG003)與染色細胞(染劑：SYTO16、SYTO62、CFSE)當作樣本並以波長為488 nm與635 nm之光纖雷射作為激發光源。

根據實驗結果可得知，使用雷射檢測螢光粒子及染色細胞時，能透過反射鏡面產生反射訊號，從樣本激發出的螢光訊號也能與反射訊號同步被檢測出，這些數據可以幫助我們進行樣本的計數、分析及分選，以達到本研究開發微流式細胞儀之目的。

In this research develop a microflow cytometry system consisting of a hand-held pipette and a micro-channel chip. It is integrated into optical signal transmission module with optical fiber, fiber laser, optical filter, reflective optical mirror and photomultiplier tube.

The micro-channel chip is made by hot pressing with a micro-tips to achieve low cost, small size and easy replacement. In this research develop, fluorescent particles(F8843、UMDG003)and stained cells(SYTO16、SYTO62、CFSE)were used as samples and fiber laser with wavelengths of 488 nm and 635 nm were used as excitation sources.

According to the experimental results, when using laser to detect the fluorescent particles and the stained cells, the sample can generate a reflection signal by the reflective optical mirror surface, and the fluorescent signal excited from the sample can also be detected with the reflection signal at the same time. These data can help us to count, analyze and sort the samples to achieve the purpose of develop microflow cytometry.
