Nanotechnology is an area that has been the subject of numerous studies and various revolutionary developments. Nanoparticles have been employed in a variety of applications such as drug delivery, chemistry, biological sensing, and gas sensing, and are an important material behind current technology. This project aimed to develop novel nanomaterials for glucose biosensor applications. The number of diabetics in Japan will reach 7.39 million (5.6%) by 2019, and the number of diabetics worldwide is also increasing, making glucose sensors an essential tool as the global diabetes problem grows. In recent years, much attention has been paid to employing various nanomaterials such as gold nanoparticles and carbon nanotubes to improve the performance of glucose sensors.

Prof. Hsu and my master degree supervisors started research cooperation on development of photocatalysts in 2012. Prof. Hsu is an expert in designing band structures of semiconductors, and my supervisors are specialized on electrodeposition of functional materials. We began to work development of catalysts for glucose sensors in 2020. I wanted to visit National Yang Ming Chiao Tung University (NYCU) for this project and work with Prof. Hsu because I believed that I could precisely control the properties of catalytic metal oxide nanoparticles and gain new insights into the development of catalytic functional composite materials.
