摘要

網版印刷碳電極（Screen-printed carbon electrodes，簡稱SPCE），具成本低廉、製程簡單、造型自由和一次性使用等優點，在現今的學術領域以及商業化傳感器中佔有很重要的地位。但SPCE的碳膠中為了使碳粉粉末附著於基版上使用了許多疏水性的高分子膠而影響電極的再現性及靈敏度。
在本篇研究中，將分別探討Poly-L-lysine、Polymelamine以及Gold nanoparticles修飾於電極表面，探討修飾膜對SPCE電化學特性的影響及電極保存的穩定性。篩選出最適當的基材並探討應用於瘦肉精的偵測之可行性。

Screen-printed carbon electrodes (SPCE) play an important role in academic research and development of commercial sensors because of the advantages of low cost, simple process, freedom of modeling and one-time use. However, carbon powder was attached to the electrode substrate of SPCE with the use of hydrophobic macro molecular, adhesive, affecting the reproducibility and sensitivity of SPCE.
In this study, poly-L-lysine, poly-melamine, and gold nanoparticles were modified on the surface of the electrode to change the electrochemical properties of SPCE and storage stability. The feasibility study of β-agonist detection was investigated using the modified SPCE.
