Abstract: This paper presents a microfabricated reservoir-type oxygen sensor, which can accurately measure the solubilized oxygen concentration in real time, in order to measure the cellular oxygen consumption rate(OCR) in a solution containing cells. The fabricated oxygen sensor is composed of three-parts: electrochemical This paper presents a microfabricated reservoir-type oxygen sensor, which can accurately measure the solubilized oxygen concentration in real time, in order to measure the cellular oxygen consumption rate (OCR) in a solution containing cells. The fabricated oxygen sensor is composed of three-parts: electrochemical sensing electrodes, an oxygen-permeable membrane, and a reservoir for storing the solution. The oxygen transport rate through the membrane and the oxygen reaction rate at the working electrode (WE) surface are the two dominant parameters in determining the sensitivity of the oxygen sensor. The fabricated sensor showed a sensitivity of 2.84 A/cm2M and a 90% response time of 4.9 s in an average of 5 sensors when a 25,000µm2 WE and a 20µm polydimethylsiloxane membrane were used. This is the first report in which the fastest response time has been achieved for the oxygen sensor. The fabricated sensor showed the repeatability with 154.05±1.87 nA at the full-oxygen state and 2.77±1.0 nA at the zero-oxygen state. The fabricated sensor was used to measure the uncoupled OCR of the L6 cells, and its result of 3.69±0.30 was almost identical to the result of 3.70±0.26 obtained from a commercial system. first report in which the fastest response time has been achieved for the oxygen sensor.
