“…Liu et al reported a composite PANI/PMMA (poly(methyl methacrylate)) to reduce this pH-effect [39]. Numerous efforts for functionalization of PANI composites [40][41][42][43][44] have been devoted to further enhancing the analytical performance. Other CPs, for example, polyazulene [45,46], ferrocene-functionalized poly(vinyl chloride) (PVC) [47] are also proposed for the SC-ISEs.…”

Wearable sensors based on solid-contact ion-selective electrodes (SC-ISEs) are currently attracting intensive attention in monitoring human health conditions through real-time and non-invasive analysis of ions in biological fluids. SC-ISEs have gone through a revolution with improvements in potential stability and reproducibility. The introduction of new transducing materials, the understanding of theoretical potentiometric responses, and wearable applications greatly facilitate SC-ISEs. We review recent advances in SC-ISEs including the response mechanism (redox capacitance and electric-double-layer capacitance mechanisms) and crucial solid transducer materials (conducting polymers, carbon and other nanomaterials) and applications in wearable sensors. At the end of the review we illustrate the existing challenges and prospects for future SC-ISEs. We expect this review to provide readers with a general picture of SC-ISEs and appeal to further establishing protocols for evaluating SC-ISEs and accelerating commercial wearable sensors for clinical diagnosis and family practice.

“…Then the wire was dipped in saturated solution of copolymer aniline(CPANI) and 2,5-dimethoxyanilineas the second layer. Finally, Ammonium ionophore I (6.9%), Potassium tetrakis (4-chlorophenyl) borate (0.7%) and 2-Nitro phenyloctyl ether (92.4%) was dissolved in N,N-Dimethyl formamide (DMF) and the wire dipped into this solution to form the third layer (Huang et al, 2015).…”

Freshwater quality detection is important for pollution control. Three important components of water quality are pH, ammonia and dissolved HS and there is an urgent need for a high-precision sensor for simultaneous and continuous measurement. In this study, all-solid-state electrodes of Eh, pH, NH and S were manufactured and mounted to a wireless chemical sensor with multiple parameters. Calibration indicated that the pH electrode had a Nernst response with slope of 53.174 mV; the NH electrode had a detection limit of 10 mol/L (Nernst response slope of 53.56 mV between 10 to 10 mol/L). Ag/AgS has a detection limit of 10 mol/L (Nernst response slope of 28.439 mV). The sensor was cylindrical and small with low power consumption and low storage demand to achieve continuous in-situ monitoring for long periods. The sensor was tested for 10 days in streams at Trawsgoed Dairy farm in Aberystwyth, UK. At the intensively farmed Trawsgoed, the concentration of NH in the stream rose sharply after the application of slurry to adjacent fields. Further, the stream was overhung with extensive vegetation and exhibited changes in pH, which correlated with photosynthetic activity. Measurements of S were stable throughout the week. Our data demonstrate the applicability of our multiple electrode sensor.

“…As a result, there is a global cause of concern in research to synthesize metal nanoparticles using green tools. Among the green methods used in the synthesis of metal nanoparticles are the use of phytochemicals [1], enzymes, bacteria, and biopolymers [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. All are used as both reducing and capping agent in the synthesis of metal nanoparticles.…”

A novel method for the preparation of conductive methyl cellulose-silver nanoparticles-polyaniline-nanocomposite

et al. 2020

A NOvel green method for the synthesis of conductive nanocomposite-using silver nitrate, methyl cellulose (MC), glycerol, and aniline-was adopted. Here, silver nitrate was used as a precursor, methyl cellulose as both reducing and capping agent, glycerol as a co-reducing and ductility agent and water as solvent. While silver nitrate oxidizes aniline to polyaniline, it is reduced to silver nanoparticles. Doing so, both conductive polyaniline and conductive silver nanoparticle were in-situ synthesized via the formation of methyl cellulosesilver-polyaniline nanocomposite. Reproducibility of the nanocomposite revealed that the synthesis process is consistent. The nanocomposite film was characterized by FTIR, SEM, eDAX, XRD, and conductivity. XRD pattern showed poly crystallinity. TeM of the colloidal solution showed different particle shapes of AgNPs with size from 4-36 nm and d-spacing of 0.22 nm. SAED exhibits ring pattern with bright spots displaying polycrystallinity. Nanocomposite film, coated glass, cotton and polyester fabrics showed promising conductivity.
