Recent advances in fused deposition modeling 3D printing (FDM 3DP) enabled
the manufacture of customized spectroelectrochemical (SEC) devices. Despite significant progress,
reported designs still rely on conventional optical components (windows and cuvettes). In this
work, we apply bi-material FDM 3DP combining electrically conductive and optically
translucent filaments to manufacture a fully integrated microfluidic SEC device. Employing cyclic
voltammetric measurements with redox probes, we demonstrate that the platform allows SEC sensing of
reactants, intermediates, and products of charge transfer reactions in an oxygen- free
environment. Developed approaches pave the way for SEC d vices with dramatically
reduced costs compared to currently available commercial platforms.
