3 . an elementary attempt has been made to enhance the signa - to - noise ratio of pqc sensors using cholestyramine particles embedded in the sensing film . bor more , an all - purpose sulpha - drugs pqc sensor was developed whch can be used for screening practice 对如何提高基于离子对缔合物的压电药物传感器的信噪比进行了初步探索，发现在传感膜层嵌入考来烯胺树脂颗粒对磺胺药物压电传感器的信号有明显的扩增作用。
