麻黄碱离子敏感场效应管传感器的研究(英文)
Study on ephedrine sensor by ion sensitive field effect transistor
【摘要】 报道了一种麻黄碱药物场效应管传感器。将药物敏感膜与离子敏感场效应管相结合,用tri-o-e-β-CD修饰传感器,测定麻黄碱。传感器对麻黄碱的线性响应范围是1.0×10-1～3.0×10-6mol/L,响应灵敏度为58.0 mV/pC（C的单位为mol/L）,适宜pH范围为3.0～8.0。用所研制的传感器测定麻黄碱片剂的含量,结果和药典方法相一致。
【Abstract】 This paper is about the development of a kind of DrugFET sensors of ephedrine by the combination of ISFET and drug sensitive membranes. The modified ISFET of tri-o-e-β-CD is made, and used to analysis ephedrine . The sensors exhibits Nernst response for ephedrine with a slop of 58. 0 mv/decade over the concentration ranges of 1. 0× 10-1-3. 0× 10-6 mol/L at pH 3. 0-8. 0. It has been used for determination of ephedrine in the table . The results obtained agree with the pharmacopoeia method.
