In this work, we report an original strategy for the wireless electrochemical generation of light at the tip of an optical fiber bundle, coupled with a simultaneous remote readout. An optical fiber bundle coated with a nanometer-thin gold film acts as a dual platform, on the one hand to locally generate electrochemi-luminescence (ECL) in a wireless manner by bipolar electrochemistry, and on the other hand to guide the resulting ECL signal. The light emission is triggered and collected at one end, transmitted by the wave-guide and remotely detected at the opposite end. Integration of both functionalities at the level of the same miniaturized object leads to an unprecedented bipolar opto-electrode, allowing one to quantify the ECL intensity as a function of different parameters in a double remote approach with interesting potential applications, ranging from high-throughput catalyst screening to massive parallel biochemical analysis.
