3D-Printed Dual-Channel Flow-Through Miniaturized Devices with Dual In-Channel Electrochemical Detection.

ABSTRACT: Here, we present three-dimensional-printed dual-channel flow-through miniaturized devices (3D_d) with dual electrochemical detection (ED_d) integrating two working electrodes each in an in-channel configuration (3D_d-ED_d). Prussian Blue (PB) shell-gold nanoparticles ((PB)AuNP) core-based electrochemistry was chosen for selective hydrogen peroxide determination. 3D_d-ED_d devices exhibited impress stability, identical intrachannel and interchannel electrochemical performances, and excellent interdevice precision with values under 9%, revealing the reliability of the design and fabrication of the devices. 3D_d-ED_d enabled long-term reliable hydrogen peroxide determination at physiological pH in Caco-2 cells und
