Simultaneous Sensing of Codeine and Diclofenac in Water Samples Using an Electrochemical Bi-MIP Sensor and a Voltammetric Electronic Tongue

Codeine and diclofenac overdoses have been widely reported. Here, a biomimetic sensor (bi-MIP) was devised, an electronic tongue used to analyze water samples simultaneously containing both these drugs. The bi-MIP limits of detection for codeine taken individually were 0.01 µg/mL 0.16 µg/mL, respectively. Due cross-reactivity effect when using the sensor, shown differentiate analytes. results confirm feasibility simultaneous two target analytes via sensor. Additionally, they demonstrate ability multi-sensor classify different samples.
