“…As a water layer The same trend in sensor response is seen after storing the electrode under wet conditions, only this time with significantly lower sensitivity values. More specifically, a decrease in sensitivity of 10 mV/decade was observed in all the electrodes tested, which can be attributed to the water uptake of the solid contact layer [36]. Compared to the negligible water uptake of the graphite disc electrode without solid contact (Figure S2), we see that the graphite-PVB layer is detrimental for the water uptake, which can in turn affect continuous measurements.…”

A planar solid-state ammonium-selective electrode, employing a composite mediator layer of graphite particles embedded in a polyvinyl butyral matrix on top of an inkjet-printed silver electrode, is presented in this paper. The effect of graphite powder mass fraction on the magnitude of the potentiometric response of the sensor was systematically verified using a batch-mode and a flow injection measurement setup. Under steady-state conditions, the paper electrode provided a Nernstian response of 57.30 mV/pNH4 over the concentration range of 10−5 M to 10−1 M with a detection limit of 4.8 × 10−6 M, while the analytical performance of the array in flow mode showed a narrower linear range (10−4 M to 10−1 M; 60.91 mV/pNH4 slope) with a LOD value of 5.6 × 10−5 M. The experimental results indicate that the prepared electrode exhibited high stability and fast response to different molar concentrations of ammonium chloride solutions. The pH-response of the paper NH4-ISE was also investigated, and the sensor remained stable in the pH range of 2.5–8.5. The potentiometric sensor presented here is simple, lightweight and inexpensive, with a potential application for in-situ analysis of environmental water samples.

“…Most of the reported SCISEs with conductive polymers use plasticized poly(vinyl chloride) (PVC) as the ion-selective membrane (ISM) [26][27][28]. However, the PVC-based ISEs suffer from diffusion of water through the ISM and the possible formation of a water layer or water pools at the ISM/solid-contact (SC) or SC/substrate interfaces resulting in poor potential stability and weakening of the ISM adhesion to the substrate [29,30].…”

Surfactant-Based Sensors in Chemical and Biochemical Detection

View full text Add to dashboard Cite

In recent years, surfactant-based sensors have played a vital role in every field of research. Surfactants are chemical compounds that act as an interface between the two states of matter to reduce surface tension. Surfactants are usually organic compounds that are amphiphilic in nature. To be precise, surfactant-based sensors have a wide range of applications in chemical and biochemical detection. We can assess the effectiveness and efficiency of surfactants using tensiometers, which measure surface tension. The construction and optimization of emulsions by precisely measuring the interfacial tension are carried out using various characterization methods. Biologically, pulmonary surfactants are produced by humans in the lungs to promote lung capacity. Here, our aim is to achieve a standard platform to fabricate cost-effective, high sensitivity, high stability, enhanced lifespan, reusable sensing devices with quick response characteristics. Simple, stable, cost-effective, and biodegradable properties have become prerequisites for the fabrication of effective surfactant-based sensors. In the present chapter, surfactant-based sensors and their properties with regard to classification, characterization, stability, lifetime, reuse, and their importance in the detection of chemicals and biochemicals are discussed.
