Paper-Based Fast-Flow Electrochemical Device Enabling Self-Calibrated and High-Throughput NADPH Measurements.

ABSTRACT: Microfluidic paper-based electrochemical devices (μPEDs) are transforming cost-effective and portable diagnostics. However, conventional μPEDs are limited to a single use, as the removal of analyzed solutions is challenging, preventing repeatable measurements. This study introduces a paper-based fast-flow electrochemical device (PFED) design that overcomes this limitation, enabling multiple detections within a single device without requiring external power. Unlike traditional μPEDs, the PFED integrates a plastic hollow channel with a wax-printed channel, ensuring that fluid flow is not solely dependent on capillary action. This enhanced configuration accelerates liquid transport, facilitates rapid solution exchange, and significantly improves device repeatability. Additionally, the PFED, c
