物聯網的崛起，使得各式各樣感測器的重要性不言而喻，其中，以生醫領域的感測器而言，植入性的感測器需相當好的生物相容性，這當中，鑽石這項材料悄悄得扮演起不可抹滅的腳色，鑽石具有不易受到酸鹼腐蝕、硬度最強、導熱度最佳等優越特性，再加上鑽石具有良好的生物相容性，如果鑽石能製作成生醫領域的植入性感測器，將具有良好的可靠度及穩定性。
生醫領域的範疇中取決於鑽石的電化學特性，而鑽石除了具有良好的生物相容性，用鑽石製備之電極或感測器具有極寬的工作電位窗和極低的背景電流，再輔以良好的物理及化學穩定性，進行硼摻雜之後，這些特性也能獲得提升，使得鑽石電極之電化學特性廣泛研究於生醫領域。
本篇論文以微波電漿化學氣相沉積系統，調整出穩定的參數製備微米之鑽石薄膜，並且進行硼摻雜鑽石的製程，於製程結束確認其相關特性，並進行電化學中循環伏安法的量測樣品製備，在不同的電解液當中分析其電荷交換的能力和工作電位窗的表現。
本文調配赤黃血鹽、多巴胺、尿酸、氯化鉀等不同電解溶液，置入有不同程度硼摻雜鑽石電極之樣品、未摻雜鑽石電極和鉑工作電極，使用恆電位儀分析其循環伏安法特性，觀察硼摻雜鑽石的電化學特性。

Nowadays, Internet of things (IOT) is the most popular issue in our life. A wide range of sensors would play an important role in IOT. In the field of biotechnology, the implant sensors need very good biocompatibility and that is why diamond could be a choice to be an implant sensor. Diamond has a lot of good advantages, such as excellent hardness, good chemical stability and high thermal conductivity. Last but not least, biocompatibility is the reason why we used diamond. If diamond could be an implant sensor to detect different bio-materials, diamond may have a good reliability and stability.
In the field of biotechnology, not only the good biocompatibility diamond has, but also the good characteristic of electrical chemistry should be discussed. Diamond has wide potential window and low background current which means diamond has good potential to detect many bio-materials. When diamond is treated by different process, such as boron doping. The performance could be better.
In this study, we try to use microwave plasma chemical vapor deposition system to grow boron doped diamond films on silicon wafer. After the growing process, we do some test to check the characteristics of boron doped diamond. Then we used boron doped diamond to create sensor to do cyclic voltammetry (CV) test. Check the boron doped diamond’s behavior of electrical chemistry in different electrolyte. We also use sputter to grow platinum film on SiO2 and use it to do CV test. Compare the electrical chemistry behavior between boron doped diamond and Pt electrode.
