“…Also when combined with other available detection methods, the increased sensitivity of PADs makes it possible to be used for quantitative analyses with almost always instantaneous results/measurements . A miniaturized chemiluminescence detection system for Cr(III) ions on a microfluidic PAD had been developed and the micro PADs (μ PADs) were used to determine Cr(III) level in tap water and other water bodies . The results obtained were comparative to that obtained by inductively coupled plasma optical emission spectroscopy (ICP‐OES).…”

Microfluidic systems have advanced beyond natural and life science applications and lab‐on‐a‐chip uses. A growing trend of employing microfluidic technologies for environmental detection has emerged thanks to the precision, time‐effectiveness, and cost‐effectiveness of advanced microfluidic systems. This paper reviews state‐of‐the‐art microfluidic technologies for environmental applications, such as on‐site environmental monitoring and detection. Microdevices are extensively used in collecting environmental samples as a means to facilitate detection and quantification of targeted components with minimal quantities of samples. Likewise, microfluidic‐inspired approaches for separation and treatment of contaminated water and air, such as the removal of heavy metals and waterborne pathogens from wastewater and carbon capture are also investigated.

“…24 With regard to Cr analysis using μPADs, several methods have been reported. [29][30][31][32][33] Alahmad et al 29 used wax-printed μPADs, and detected Cr III into natural water by chemiluminescence. Colorimetric detection, which was reported by Henry's group, [30][31][32] is simple, and gray scale intensity analysis is often carried out using image-processing software.…”

Microfluidic Paper-based Analytical Device for the Determination of Hexavalent Chromium by Photolithographic Fabrication Using a Photomask Printed with 3D Printer

This article describes a simple and inexpensive microfluidic paper-based analytical device (μPAD) for the determination of hexavalent chromium (Cr VI ) in water samples. The μPADs were fabricated on paper by photolithography using a photomask printed with a 3D printer and functionalized with reagents for a colorimetric assay. In the μPAD, Cr VI reacts with 1,5-diphenylcarbazide to form a violet-colored complex. Images of μPADs were captured with a digital camera; then the red, green, and blue color intensity of each detection zone were measured using images processing software. The green intensity analysis was the best sensitive among the RGB color. A linear working range (40 -400 ppm; R 2 = 0.981) between the Cr VI and green intensity was obtained with a detection limit of 30 ppm. All of the recoveries were between 94 and 109% in recovery studies on water samples, and good results were obtained.

“…21 One of the most serious problems with PADs is detectability, which is poorer than that in conventional spectrophotometry. To solve this problem, sensitive detection methods, including electrochemistry, [22][23][24][25][26] chemiluminescence, [27][28][29] and electrochemiluminescence [29][30][31] have been coupled with PADs. Although these detectors can be potentially miniaturized by sophisticated technologies, batteries are absolutely necessary to drive the detectors.…”

The implementation of continuous flow in paper-based analytical devices (PADs) was challenging because of the largevolume introduction that was created; but this allowed for the development of novel types of PADs for preconcentration, separation, and sensitive detection. In this study, pump-free continuous flow was applied to a distance-based PAD for the determination of iron ions. Continuous flow enabled the introduction of a volume that exceeded what was necessary to fill the hydrophilic channel of a PAD. Thus, this continuous-flow method significantly improved both the limits of detection (LOD) and the limits of quantification (LOQ) for a distance-based PAD by increasing the sample volume that could be introduced into the PAD. The values for LOD and LOQ were 20 and 26 ppb, respectively, which were more than 150-times lower than that obtained using a small sample volume (50 μL), and were comparable to those of inductively coupled plasma-atomic emission spectrometry. The continuous-flow technique was applicable to the determination of iron ions at levels of several tens of ppb in natural water without preconcentration.
