“…Evanescent wave fiber optic biosensors have become powerful analytical tools in medical diagnosis, environmental monitoring, and food safety because of their high sensitivity and specificity, easy-to-operation, and potential for point-of-care testing [ [21] , [22] , [23] ]. Recently, an optofluidic pointing-of-care testing platform (OPOCT) was developed and the potential in medical testing has been demonstrated from the rapid detection of cholylglycine (CG) in serum [ 24 ].…”

The COVID-19 pandemic brings unprecedented crisis for public health and economics in the world. Detecting specific antibodies to SARS-CoV-2 is a powerful supplement for the diagnosis of COVID-19 and is important for epidemiological studies and vaccine validations. Herein, a rapid and quantitative detection method of anti-SARS-CoV-2 IgG antibody was built based on the optofluidic point-of-care testing fluorescence biosensor. Without complicated steps needed, the portable system is suitable for on-site sensitive determination of anti-SARS-CoV-2 IgG antibody in serum. Under the optimal conditions, the whole detection procedure is about 25 min with a detection limit of 12.5 ng/mL that can well meet the diagnostic requirements. The method was not obviously affected by IgM and serum matrix and demonstrated to have good stability and reliability in real sample analysis. Compared to ELISA test results, the proposed method exhibits several advantages including wider measurement range and easier operation. The method provides a universal platform for rapid and quantitative analysis of other related biomarkers, which is of significance for the prevention and control of COVID-19 pandemic.

“…Concrete degradation is a complex process that results from physical and chemical reactions between concrete components and their surrounding environment. The corrosion of steel in reinforced concrete structures (RCS) has been widely studied and reported by several authors [1][2][3][4][5][6][7], since its premature degradation often results in expensive costs of repair, maintenance, and rehabilitation. To mitigate corrosion in RCS and improve their service life, different approaches-destructive and non-destructive methods-have been developed with the aim of monitoring both existing and new structures.…”

“…To mitigate corrosion in RCS and improve their service life, different approaches-destructive and non-destructive methods-have been developed with the aim of monitoring both existing and new structures. Destructive methods provide information about the corrosion process [3,8]. Nevertheless, some constraints exist due to the heterogeneity of RCS and to the fact that the structures are limited to sampling [3].…”

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.

Fiber optic sensors are widely used in environmental, biological and chemical sensing. Due to the demanding environmental conditions in which they can be used, there is a risk of damaging the sensor measurement head placed in the measuring field. Sensors using nanolayers deposited upon the fiber structure are particularly vulnerable to damage. A thin film placed on the surface of the fiber end-face can be prone to mechanical damage or deteriorate due to unwanted chemical reactions with the surrounding agent. In this paper, we investigated a sensor structure formed with a Zinc Oxide (ZnO) coating, deposited by Atomic Layer Deposition (ALD) on the tip of a single-mode fiber. A nanocrystalline diamond sheet (NDS) attached over the ZnO is described. The diamond structure was synthesized in a Microwave Plasma Assisted Chemical Vapor Deposition System. The deposition processes of the nanomaterials, the procedure of attaching NDS to the fiber end-face covered with ZnO, and the results of optical measurements are presented.
