Outline of Final Research Achievements

We found that Ni nanoparticles formed on the nitrogen doped (N-doped) carbon film shows higher electrocatalytic activity compared with nanoparticles on the pure carbon film, and applied for developing wearable glucose sensor. Ni nanoparticles formed on N-doped carbon film show higher crystallinity than those on pure carbon film. Furthermore, the former electrode shows higher electrocatalytic current than latter electrode even at one order of magnitude lower pH. In order to develop calibration free sensor, we employed nitrogen plasma treated carbon felt with high surface area and electrodeposited Ni nanoparticles and confirmed improved electrocatalytic activity for sugars like Ni nanoparticles modified N-doped carbon film.

Academic Significance and Societal Importance of the Research Achievements

本研究では、カーボン電極表面をプラズマ処理により窒素化した後、糖酸化特性を有するNiナノ粒子を修飾すると窒素化する前に比べて高い糖酸化特性を実現し、より低いpHでも特性の向上が見られた。これらの結果は、電極触媒活性向上の手段として異議深いと共にウエアラブル糖センサの様な連続測定が必要なバイオセンサの電極として社会的意義がある。更に大面積の電極でも効果を確認したことは、センサへの応用だけでなく、糖やアルコールを燃料とする燃料電池の電極への応用の可能性もある。
