磷脂氧化的检测对于肉品质量控制和疾病预防具有重要意义。本文设计并制作了一种基于可印刷介观芯片（PMC）的快速实时监测磷脂氧化的光电化学传感器。在FTO玻璃上逐层丝网印刷TiO 2、ZrO 2和PMC碳膜。采用扫描电镜（SEM）、紫外-可见光谱（UV-vis）、循环伏安（CV）和电化学阻抗谱（EIS）等方法研究了PMC及其测定磷脂氧化程度的可行性。与其他方法相比，该方法不需要对PMC中的磷脂进行预处理，且过程无损、实时。该方法灵敏度高，选择性好。PMC的制造工艺简单，成本相对较低。
The detection of phospholipids oxidation is important for meat control and disease prevention. In this paper, a photoelectrochemical sensor based on printable mesoscopic chip (PMC) for fast and real-time monitoring phospholipids oxidation was designed and fabricated. TiO2, ZrO2and carbon films of PMC were screen-printed onto the FTO glass layer by layer. The PMC and the feasibility for determination of phospholipids oxidation were investigated by scanning electron microscope (SEM), UV–visspectroscopy, cyclic voltammograms (CVs) and electrochemical impedance spectroscopy (EIS), etc. The short circuit current (Jsc) was used as a signal current, which would decrease if phospholipids in PMC were undergoing oxidation for the change of electrical properties. Compared with other methods, phospholipids in PMC did not require pretreatment, and the process was nondestructive and real-time. Meanwhile, this method showed high sensitivity and good selectivity. The fabricating process of PMC is simple, and the costs are low, relatively.
