摘要：
This paper reports on pH-sensitive thin films of sputter-deposited TiO2 on indium tin oxide electrodes for biosensor applications. The composition and crystallographic properties of the TiO2 thin films were controlled by varying the substrate temperature and total pressure used for sputtering. The pH sensitivity and potential drift of TiO2 thin films with different ratios of anatase to rutile phases were compared. It was found that the TiO2 films with a predominant rutile phase exhibited low drift characteristics and those with a predominant anatase phase exhibited high sensitivity and lower hysteresis. Furthermore, lactate sensing using lactate dehydrogenase immobilized on TiO2 thin films was demonstrated. © 2021 The Institute of Electrical Engineers of Japan.
