“…Sensors for metal cation detection possess ionophores sensitive and selective towards target ions, and measurement of the optical or electrochemical response of ion-ionophore complex is at the heart of modern analytic techniques. [3][4][5][6][7][8][9][10][11][12][13][14][15][16] Mg 2+ and other metal cation traps attract the cation by their electronegative atoms within, for example, coumarin derivatives, [4][5][6][7] Schiff bases, [8][9][10] or cyclic ethers. [11][12][13] The latter, known as crown ethers, 17 proved successful in cation capture [18][19][20][21][22][23][24][25][26] due to the negative charge concentrated in the center of the ring.…”

“…The electrode designs of these wearable sensors have been varied depending on the application of the wearable sensors. Some common electrode designs include interdigital, serpentine, and circular nature to assist the sensors in their use for resistive [ 98 , 99 , 100 ], capacitive [ 101 , 102 , 103 ], and impedance [ 104 , 105 , 106 ] measurements. The integration of software with wearable sensors helps in improving the health, quality of life, and quality of care.…”

This paper presents a substantial review of the deployment of wearable sensors for healthcare applications. Wearable sensors hold a pivotal position in the microelectronics industry due to their role in monitoring physiological movements and signals. Sensors designed and developed using a wide range of fabrication techniques have been integrated with communication modules for transceiving signals. This paper highlights the entire chronology of wearable sensors in the biomedical sector, starting from their fabrication in a controlled environment to their integration with signal-conditioning circuits for application purposes. It also highlights sensing products that are currently available on the market for a comparative study of their performances. The conjugation of the sensing prototypes with the Internet of Things (IoT) for forming fully functioning sensorized systems is also shown here. Finally, some of the challenges existing within the current wearable systems are shown, along with possible remedies.

“…Organic pollutants, particularly persistent organic pollutants (POPs), have harshly harmful impacts on human health and the environment with their complex degradation and potential bioaccumulation [ 8 ]. The biochemical oxygen demand (BOD) is the essential supervisory index to measure organic water contamination and demonstrate water quality [ 9 , 10 ]. Water quality monitoring is critical and closely related to our life and production.…”

The release of chemicals and microorganisms from various sources, such as industry, agriculture, animal farming, wastewater treatment plants, and flooding, into water systems have caused water pollution in several parts of our world, endangering aquatic ecosystems and individual health. World Health Organization (WHO) has introduced strict standards for the maximum concentration limits for nutrients and chemicals in drinking water, surface water, and groundwater. It is crucial to have rapid, sensitive, and reliable analytical detection systems to monitor the pollution level regularly and meet the standard limit. Electrochemical biosensors are advantageous analytical devices or tools that convert a bio-signal by biorecognition elements into a significant electrical response. Thanks to the micro/nano fabrication techniques, electrochemical biosensors for sensitive, continuous, and real-time detection have attracted increasing attention among researchers and users worldwide. These devices take advantage of easy operation, portability, and rapid response. They can also be miniaturized, have a long-life span and a quick response time, and possess high sensitivity and selectivity and can be considered as portable biosensing assays. They are of special importance due to their great advantages such as affordability, simplicity, portability, and ability to detect at on-site. This review paper is concerned with the basic concepts of electrochemical biosensors and their applications in various water quality monitoring, such as inorganic chemicals, nutrients, microorganisms’ pollution, and organic pollutants, especially for developing real-time/online detection systems. The basic concepts of electrochemical biosensors, different surface modification techniques, bio-recognition elements (BRE), detection methods, and specific real-time water quality monitoring applications are reviewed thoroughly in this article.
