Electrochemical sensors have been widely employed in diverse domains of electrochemical analysis, biosensing, drug administration, healthcare, agriculture, and so on because of their special potential features that are closely related to their high selectivity, sensitivity and cycling stability. Various electrochemical techniques employed to transduct biological or chemical signal to electrical signal are voltammetry, conductometry, potentiometry and amperometry. Due to the high demand of global market and human interest in having a device to check the concentration of species in different samples that is simple and fast, researchers have been engaged in a fierce competition to design and build new sensors and biosensors in recent years. The performance of the sensors can be considerably improved by modifying the electrode surfaces using diverse nanomaterials. Further, electrochemical biosensors are promising diagnostic tools that can find biomarkers in bodily fluids including sweat, urine, blood or excrement. Nanoparticles have found propitious role in biosensors, because they aid in functions like immobilisation of molecules, catalysis in electrosynthesis, facilitation of electron transfer between electrodes and biomolecules and labelling of biomolecules. The advance in the research amalgamating electrochemistry and nanotechnology for electro (bio) sensing applications is the beginning of a promising future for mankind and global market.

“…The detection and monitoring of chloride ion (Cl − ) concentration plays an important role in several aspects, including human health [130][131][132], industrial process control [133], wasted water management [134], drinking water quality control [135,136], and corrosion forecasting of RCS [137][138][139]. There are several available methods for measuring Cl − concentration, including electrochemical sensors, OFS [28,140], and Bragg's grating [141,142].…”

The use of advanced sensing devices for concrete and reinforced concrete structures (RCS) is considered a rational approach for the assessment of repair options and scheduling of inspection and maintenance strategies. The immediate benefits are cost reduction and a reliable prevention of unpredictable events. The use of optical fiber sensors (OFS) for such purposes has increased considerably in the last few years due to their intrinsic advantages. In most of the OFS, the chemical transducer consists of immobilized chemical reagents placed in the sensing region of the optical sensor by direct deposition or by encapsulation in a polymeric matrix. The choice of the support matrix impacts directly on the performance of the OFS. In the last two decades, the development of OFS functionalized with organic–inorganic hybrid (OIH) sol–gel membranes have been reported. Sol–gel route is considered a simple method that offers several advantages when compared to traditional synthesis processes, allowing to obtain versatile materials with unique chemical and physical properties, and is particularly valuable in the design of OIH materials. This review will provide an update of the current state-of-the-art of the OFS based on OIH sol-gel materials for concrete and RCS since 2016 until mid-2021. The main achievements in the synthesis of OIH membranes for deposition on OFS will be discussed. The challenges and future directions in this field will also be considered, as well as the main limitations of OFS for RCS monitoring.
