TMAO is believed as an oxidation intermediate of trimethylamine. Because of this, the contents of trimethylamine and/or TMAO in sea foods are regarded as a symbol of freshness. The detection of TMAO thus becomes an important analytical issue currently. In this thesis, we successfully prepared phenothiazine-modified electrodes and used them to analyze the concentration of TMAO. Experiment results show that poly(methylene blue) is an effective mediator for the reduction of TMAO. The linear calibration range covers 0.001∼1 M. The detection limit may reach a level of 10-4 M. Poly(methyl violet) also shows a similar catalytic potential. The linear calibration range covers 10μM∼10 mM. The dection limit is about 10μM. Chong Mou Wang 王忠茂 2003 學位論文 ; thesis 74 zh-TW
