Plasmonic-assisted electrochemical detection of hydrogen peroxide
Plasmonic nanostructures are widely studied in opto-electrical sensing and biosensing. Despite their enhanced optical and electromagnetic properties, the complexity of fabrication hinders their integration into cost-effective and scalable electrodes. Here, we focus on a fabless approach to develop a hybrid structure of gold (Au) plasmonic nanocavities and graphene nanosheets for the plasmonic assisted electrochemical detection of hydrogen peroxide (H2O2). The electrode is integrated into a portable microfluidic device and validated via the effective H2O2 detection released from cancer cells.
