“…These results were consistent with our previous studies. 31,32 The ISEs we used in this paper showed a slight deviation from the ideal (59,16 mV/decade) value. This can be attributed to the membrane composition and the ratio of the materials used within.…”

In this work, we proposed a new wireless sensor to contribute to research aimed at continuous monitoring of nitrate and ammonium in water, which are important agents causing water pollution, which is a very important problem today. In this research, a well-implemented application of electroanalytical sensor was achieved by combining it with the internet of things (IoT) concept, which is the most modern form of wireless data collection technique. We developed a portable IoT system and ion-selective nitrate and ammonium electrodes and monitored the nitrate and ammonium levels of the water online. The system was produced in a low-cost manner (under $25) and it enabled data acquisition without energy related problems, thanks to the support of solar energy and mobile power bank. The recovery rates of the sensors were tested with the standard addition method and response was obtained between 101.74% and 147.01%.

“…Despite the relative ease of modification and the popularity of PVC as membrane matrix, there is only a handful of reports about poly(vinyl chloride) modification (aminated 29–37 and azidated 38–42) in the ISE field. Additionally, commercial PVC containing 1.8 % of carboxylic acid groups was used for further functionalization 18, 21, 43–54.…”

Membrane/sample interactions play a crucial role in the biomedical application of ion selective electrodes (ISEs). Modulation of membrane surface properties can be used as a way to enhance biocompatibility and in fabrication of biosensors through biomolecules immobilization. This review discusses advances in methods and materials used for the surface modifications of polymeric ion-selective membranes in view of their applications in clinical diagnostics
