Design and Application of a Flexible Sensor for Glucose Detection

[[abstract]]本研究開發出一可撓式葡萄糖感測器，以溶氧感測(Dissolved oxygen)原理為基礎，利用聚對二甲苯(Parylene)為底材，在基材上沉積金屬作為電極(Electrode)，並調配出葡萄糖氧化酵素膜(Glucose oxidase film)，將其塗佈於金屬感測電極上，完成可撓式葡萄糖感測器之製作。將製作完成之可撓式葡萄糖感測器置於磷酸鹽緩衝液(PBS) 之中，水溫26℃，並量測10-4 M、10-3 M、5×10-3 M、10-2 M之葡萄糖濃度，驗證此葡萄糖感測晶片之性能。 根據結果顯示，利用循環伏安法(Cyclic Voltammetry)，於不同葡萄糖濃度之PBS中量測結果，繪製出電流與葡萄糖濃度之校正曲線圖，藉由此曲線圖計算出可撓式葡萄糖感測晶片之靈敏度為 2 53 μA mM-1cm-2、線性關係R2為0 9858。[[abstract]]A flexible dissolved oxygen sensor is developed in this study based on electrochemical principles parylene is used as the substrate the metal as the electrode This flexible glucose sensor is completed The flexible glucose sensor is achieved at 26℃ and measuring 10-4 M、10-3 M、5×10-3 M and 10-2 M of glucose concentration Cyclic voltammetry applied in different dissolved glucose concentration thus obtaining the calibration range to dissolved glucose from 10-4 M~10-2 M The result shows that a sensitivity of 2 53 μA mM-1cm-2 the linearity with a correlation coefficient of 0 985
