A team of researchers has developed a compact, self-powered electrochemiluminescence (ECL) device that detects toxic amines in water using only the energy generated by the liquid flow itself, eliminating the need for external electricity. Study: An electrochemiluminescence device powered by streaming potential for the detection of amines in flowing solution. What sets it apart is that it doesn’t need an external light source: luminescence is triggered electrochemically. A Self-Powered ECL SolutionIn this study, the team developed and optimized a microfluidic ECL device that can detect amines in flowing liquids without needing external electricity or a potentiostat. What’s most notable is that this entire process doesn’t require any external power.
