Abstract

Diclofenac is a widely used pharmaceutical pollutant that is frequently detected in wastewater and natural
waters; however, its reliable on-site quantification remains challenging because of costly instrumentation, labor intensive sample preparation, and electrodes with limited electron-transfer efficiency. In this study, we report a simple, scalable, and mask-free strategy for constructing high-performance electrochemical electrodes based on laser-induced graphene (LIG) produced by direct laser graphene writing on polyimide.
