“…Up to now, several methods have been well developed for fabrication of μCADs, including weaving (Bhandari et al, 2011;Owens et al, 2011;Vatansever et al, 2012), batik painting (Nilghaz et al, 2012(Nilghaz et al, , 2015Bagherbaigi et al, 2014;Malon et al, 2014), stereo-stitching (Xing et al, 2013), wax screen-printing (Guan et al, 2015), and photolithography (Wang et al, 2014;Baysal et al, 2014aBaysal et al, , 2014bBaysal et al, , 2015Wu and Zhang, 2015). The as-manufactured μCADs combine the simplicity of cloth strip tests and the complexity of the conventional lab-on-chip devices, and as a result become a class of microfluidic systems.…”

“…The as-manufactured μCADs combine the simplicity of cloth strip tests and the complexity of the conventional lab-on-chip devices, and as a result become a class of microfluidic systems. Moreover, these μCADs are capable of performing a series of biochemical assays or other applications, such as immunoassay (Bhandari et al, 2011;Bagherbaigi et al, 2014), detection of glucose or protein in artificial urine (AU) (Nilghaz et al, 2012(Nilghaz et al, , 2015Wu and Zhang, 2015), assay of hydrogen peroxide (H 2 O 2 ) (Baysal et al, 2015;Guan et al, 2015), lactate measurement in saliva (Malon et al, 2014) or phosphate buffer solution (PBS) (Baysal et al, 2014a(Baysal et al, , 2014b, removal of sweat on an artificial skin surface (Xing et al, 2013), pH sensitive liquid transport (Vatansever et al, 2012), and liquid-liquid extraction (Owens et al, 2011).…”

“…Possibly because of its simplicity, colorimetric detection is the most used method in μCADs (Bhandari et al, 2011;Nilghaz et al, 2012Nilghaz et al, , 2015Bagherbaigi et al, 2014;Baysal et al, 2014aBaysal et al, , 2014bBaysal et al, , 2015Wu and Zhang, 2015), where specific reagents are applied to the device and the developed color intensity and/or hue correlates with analyte concentration. In general, however, only qualitative or semiquantitative measurement can be obtained.…”

The rising need for low-cost diagnostic devices has led to the search for inexpensive matrices that allow performing alternative analytical assays. Cloth is a viable material for the development of analytical devices due to its low material and manufacture costs, ability to wick assay fluids by capillary forces, and potential for patterning multiplexed channel geometries. In this paper, we describe the construction of low-cost, ultraflexible microfluidic cloth-based analytical devices (μCADs) for wireless electrochemiluminescence based on closed bipolar electrodes (C-WL-ECL), employing extremely cheap materials and a manufacturing process. The C-WL-ECL μCADs are built with wax-screen-printed cloth channels and carbon ink screen-printed electrodes, and the estimated cost per device is only $0.015. To demonstrate the performance of C-WL-ECL μCADs, the two most commonly used ECL systems - tris(2,2'-bipyridyl)ruthenium(ii)/tri-n-propylamine (Ru(bpy)3(2+)/TPA) and 3-aminophthalhydrazide/hydrogen peroxide (luminol/H2O2) - are applied. Under optimized conditions, the C-WL-ECL method has successfully fulfilled the quantitative determination of TPA with a detection limit of 0.085 mM. In addition, on the bent μCADs (bending angle (θ) = 180°), the luminol/H2O2-based ECL system can detect H2O2 as low as 0.024 mM. Based on such an ECL system, the bent μCADs are further used for determination of glucose in a phosphate buffer solution (PBS), with the detection limit of 0.195 mM. Finally, the applicability and validity, anti-interference ability, and storage stability of the C-WL-ECL μCADs are investigated. The results indicate that the proposed device has shown potential to extend the use of microfluidic analytical devices, due to its simplicity, low cost, ultraflexibility, and acceptable analytical performance.

In this manner, sensor technologies have garnered great attention in various fields, including biomedicine, [2][3][4][5] environmental monitoring, [6][7][8][9] smart devices, [10] wearable devices, [11] automobile manufacturing [12] since the semiconductor materials and circuits have been developed. In particular, biosensors are powerful and innovative analytical tools that incorporate biological receptors to recognize biological analytes through either physical or chemical transducers. Primarily, bio-receptors are responsible for identifying and capturing target analytes, and the transducer basically translates biological and chemical information into the detectable signals, which are eventually converted into the concentration of the analyte. [13,14] Considering gold standard methods, such as enzyme-linked immunosorbent assay (ELISA) [15] and polymerase chain reaction (PCR)-based strategies, [16] biosensors mostly hold crucial features, such as i) short assay time, [17] ii) affordable tools and reagents, [18] iii) portability, [19] and iv) facile use and minimum user interpretation. [20] Nowadays, the applications of biosensors have been leveraged by the advancements of portable and miniaturized platforms. In particular, over the past years, wearable health monitoring devices have notable impact on continuous and real-time monitoring of health parameters, thereby accelerating the deployment of biosensing strategies to daily lives. Besides, non-invasive and ease-of-collecting information supports the benefits of the wearable systems for enhancing the awareness of individuals and communities. [21][22][23] The special features of the mechanically flexible and stable wearable sensors include remarkable means, such as portability, comfortability, light-weight, non-invasive, and reliable performance. To put it simply, wearable sensors are readily attached to skin or organ surfaces through an adhesive tape [24] or microneedles, [25] and because of such easy integrations, several researchers have focused on developing wearable sensors for real-time health monitoring. A wearable sensor is basically composed of some vital elements, including a flexible base material attached to the skin or an organ, a signal transfer electrode, and a biorecognition element. Recently, researchers have concentrated on creating integrated sensors that are able to measure various parameters simultaneously, such as pressure, temperature,The healthcare system has a drastic paradigm shift from centralized care to home-based and self-monitoring strategies; aiming to reach more individuals, minimize workload in hospitals, and reduce healthcare-associated expenses. Particularly, wearable technologies are garnering considerable interest by tracking physiological parameters through motion and activities, and monitoring biochemical markers from sweat, saliva, and tears. Through their integrations with sensors, microfluidics, and wireless communication systems, they allow physicians, family members, or individuals to monitor multiple parameters withou...
