Novel sensitive disposable sensors have been introduced for potentiometric determination of naproxen (NAP) based on single‐walled carbon nanotubes‐polyvinyl chloride (SWNTs‐PVC) composite incorporated of calix[4]arene as host‐guest molecular recognition element. The electrode matrix composition was optimized on the basis of the nature and content of the sensing element, cationic sites, plasticizer and nanomaterial. Remarkable selectivity and sensitivity towards NAP was achieved in the concentration range from 10−8 to 10−2 mol L−1 with anionic Nernstian compliance −61.0±0.0 mV decade−1. Modification with calixarene and carbon nanotubes improved the sensors performance through formation of NAP‐calixarene inclusion complex and promotion of the electron‐transfer processes which enhance the potential stability, response time, and shelf lifetime of the sensor. The proposed sensors were successfully applied for the potentiometric assay of NAP in dosage formulation and biological fluids under batch and flow injection analysis (FIA) conditions with average recoveries agreeable with the reported official methods.

基于新型杯芳烃/碳纳米管的丝网印刷传感器，用于流动注射电位法测定萘普生
引入了新型灵敏的一次性传感器用于电位计测定萘普生（NAP），该传感器基于杯盖[4]芳烃作为客体分子识别元件的单壁碳纳米管-聚氯乙烯（SWNTs-PVC）复合材料。根据传感元件的性质和含量，阳离子部位，增塑剂和纳米材料对电极基质的组成进行了优化。在10 -8至10 -2 mol L -1的浓度范围内达到了对NAP的显着选择性和敏感性，阴离子Nernstian顺应性-61.0±0.0 mV十年-1。杯芳烃和碳纳米管的改性通过形成NAP-杯芳烃夹杂物和促进电子转移过程而提高了传感器的性能，从而提高了传感器的潜在稳定性，响应时间和保质期。所提出的传感器已成功应用于间歇和流动注射分析（FIA）条件下的剂型和生物液体中NAP的电位测定，平均回收率与所报道的官方方法相符。
