Fabrication of ITO Micro-Pore Electrochemical Sensor and the Detection of Exocytosis

Exocytosis is one of the major means for cells to transmit messages.Amperometric detection of exocytosis is an important method in studying communication between cells.In this study a new type of ITO micro-pore electrochemical sensor was fabricated by means of ITO and UV light lithographic mask and was used in the detection of exocytosis with promising results.Compared with the conventional method,the ITO micro-pore sensor not only can replace the carbon fiber electrode,but also can combine with fluorescent or chemiluminescent methods in detecting the physiological phenomena of cells.
