摘　　要：以硅钨酸、磷钼酸为电活性物质,用壳聚糖代替传统的聚氯乙烯(PCV)作为成膜物质,制成药物敏感膜.将其与离子敏感场效应晶体管(ISFET)、离子敏感电极相结合,制成药物敏感传感器.结果表明,以壳聚糖制成敏感膜用于化学传感器有极大的应用前景.Using silicotungstic acid and phosphomolybdic acid as active material, a medical sensitive membrane is made by applying chitosan as membranous material instead of traditional PVC. Then combining it with ISFET and ionic sensitive electrode makes medical sensitive sensor. The result shows that the sensor has good response for ephedrine hydrochloride and atropine sulfate.
