Dual Chromatic Laser-Printed Microfluidic Paper-Based Analytical Device (μPAD) for the Detection of Atrazine in Water

Hichem Moulahoum

Abstract: Water pollution caused by pesticides is a significant threat to the environment and human health. Silver and gold nanoparticle (AgNPs, AuNPs)-based biosensors are affordable tools, ideal for environmental monitoring. Microfluidic paper-based devices (μPADs) are a promising approach for on-site testing, but few studies have explored the use of laser printing (LP) for μPAD-based biosensors. This study investigates the feasibility of using laser printing to fabricate paper-based biosensors for pesticide detection… Show more

“…Also, with reproducibility between 4.2%-5.5%. In addition, Moulahoum (2023) reported a method for detecting atrazine, a pesticide used for crops, based on fabricating a biosensor from a laser-printed µ-PAD chip in a Y shape using gold and silver nanoparticles as reagents for colorimetric detection (Figure 6B). The µ-PAD chip was fabricated useing a laser-printed to reduce the devices cost compared to fabrication with wax or inkjet printer.…”

“…Chang et al (2023) used integration centrifugal microfluidics with nylon filter membranes to rapidly detect live bacteria in water. The method concept was to concentrate the bacteria via a centrifugation system and then occupy them with water-soluble tetrazolium-8 (WST-8), which was used for the colorimetric detection of the bacterial metabolism so changes in (Moulahoum, 2023).
