本文利用场效应晶体管与药物敏感膜相结合.研制成一种PVC膜丁氯喘半导体传感器。该传感器具有良好的能斯特响应。传感器对丁氯喘的线性范围为5×10~(-5)-1×10~(-1)mol/L,检测下限7×10~(-5)mol/L;响应斜率为60mV/dec;适宜的pH范围为2—9。
In this paper, the combination of field-effect transistor and drug-sensitive film has been developed into a PVC film Dingchuan semiconductor sensor. The sensor has a good Nernstian response. The linear range of the sensor was 4.0 × 10 -5 mol -1 -1 and the detection limit was 7 × 10 -5 mol / L. The response slope was 60 mV / dec ; Suitable pH range is 2-9.
