Electrokinetic stacking of electrically neutral analytes with paper-based analytical device

Talanta, 2018
Electrokinetic stacking (ES) is effective for improving sensitivity of paper-based analytical device (PAD) for charged analytes. In this paper, we successfully demonstrated ES of electrically neutral analytes on PAD, and the performance was characterized by smartphone-based colorimetry and fluorescence.

Electrochemistry on Paper‐based Analytical Devices: A Review

Electroanalysis, 2016
AbstractEven though they were introduced less than a decade ago, electrochemical paper‐based devices (ePADs) have attracted widespread attention because of their inherent advantages in many applications. ePADs combine the advantages of microfluidic paper‐based devices (low cost, ease of use, equipment free pumping, etc.) for sample handling and ...

Design of paper-based analytical devices

Microfluidic paper-based analytical devices (μPADs) are a new platform for developing portable diagnostics for resources-limiting settings. These devices enable the detection of various analytes in a sample fluid by accommodating a detection system in a flow guiding pattern fabricated on a paper substrate.

The Chemiluminescence Paper-Based Analytical Device for Lead Measurement in Gasoline

Talanta
This study developed a paper-based analytical device with a chemiluminescence detection method (PAD-CL) to determine lead cations (Pb2+) in a gasoline sample. The paper substrate was modified with NiO hollow microspheres (NiO HMs) to catalyze the luminol-O2 CL reaction.
