“…Another example is the use of electrochemical techniques for detecting enzymes and hormones to monitor for pregnancy-related disease and cancer [50,51]. In comparison to traditional procedures, such as Western blot and PCR, in terms of the time and cost, an electrochemical approach is a preferable option [52].…”

The world of sensors is diverse and is advancing at a rapid pace due to the fact of its high demand and constant technological improvements. Electrochemical sensors provide a low-cost and convenient solution for the detection of variable analytes and are widely utilized in agriculture, food, and oil industries as well as in environmental and biomedical applications. The popularity of electrochemical sensing stems from two main advantages: the variability of the reporting signals, such as the voltage, current, overall power output, or electrochemical impedance, and the low theoretical detection limits that originate from the differences in the Faradaic and nonFaradaic currents. This review article attempts to cover the latest advances and applications of electrochemical sensors in different industries. The role of nanomaterials in electrochemical sensor research and advancements is also examined. We believe the information presented here will encourage further efforts on the understanding and progress of electrochemical sensors.

“…Khunseeraksal et al [ 54 ] exhibited an electrochemical biosensor that can quantify iodide ions in the urine of pregnant women through a reduction reaction of iodide ions at the GCE surface modified with silver oxide microparticles–poly acrylic acid/poly vinyl alcohol (Ag 2 OMPs-PAA/PVA) as shown in Figure 14 a. An advantage of this approach is enhancing detection sensitivity and reproducibility by entrapping nanoparticles and preventing their separation from GCE.…”

Human urine samples are non-invasive, readily available, and contain several components that can provide useful indicators of the health status of patients. Hence, urine is a desirable and important template to aid in the diagnosis of common clinical conditions. Conventional methods such as dipstick tests, urine culture, and urine microscopy are commonly used for urinalysis. Among them, the dipstick test is undoubtedly the most popular owing to its ease of use, low cost, and quick response. Despite these advantages, the dipstick test has limitations in terms of sensitivity, selectivity, reusability, and quantitative evaluation of diseases. Various biosensor technologies give it the potential for being developed into point-of-care (POC) applications by overcoming these limitations of the dipstick test. Here, we present a review of the biosensor technologies available to identify urine-based biomarkers that are typically detected by the dipstick test and discuss the present limitations and challenges that future development for their translation into POC applications for urinalysis.

“…Thus, accurate and precise quantification of I − requires a sensitive analytical method to be applicable to a large range of food products. Thus far, several methods, including ion-selective electrodes, 9,10 chromatography, 11 mass spectrometry, 12 capillary electrophoresis, 13 electrochemical detection, 14,15 and chemiluminescence detection 16,17 have been used to analyze I − . Nevertheless, these methods are time-consuming, suffer from matrix effects, and are not applicable to all product types.…”
