Distance-Readout Paper-Based Microfluidic Chip with a DNA Hydrogel Valve for AFB1 Detection

Analytical Chemistry
Accurate and rapid aflatoxin B1 (AFB1) detection is essential for ensuring the safety of food supplies. In this paper, we introduce a distance-readout paper-based microfluidic chip (DPMC) that offers a sensitive and reliable method for the detection of AFB1. The DPMC comprises a DNA hydrogel sensitive valve and a paper-based capillary channel.

Improved sensitivity in paper-based microfluidic analytical devices using a pH-responsive valve for nitrate analysis

Talanta
This paper presents an innovative application of chitosan material to be used as pH-responsive valves for the precise control of lateral flow in microfluidic paper-based analytical devices (μPADs). The fabrication of μPADs involved wax printing, while pH-responsive valves were created using a solution of chitosan in acetic acid.
