“…[37][38][39] Nanoparticles possess special characteristics and a low dimensionality that render them ideal materials for electrocatalysis. 40 For achieving precise measurements, the convergence of nanotechnology with the development of smaller, and more sensitive and precise electrochemical sensors and enhancing their selectivity and specificity for detecting target analytes is imperative through optimization of composition, 41,42 pore sizes, and functionalities to perfectly induce specific interactions with the target analyte.' The nanostructured surfaces' electrocatalytic properties facilitate easy electron and mass transfer, which may lessen overpotentials and enable peak separation between the voltammetric profiles of interferents and target analyte(s).…”

Endocrine-disrupting chemicals (EDCs) are synthetic compounds widely used in various industrial and consumer products, raising concerns about their potential adverse effects on human health and the environment. Among the numerous EDCs, Bisphenols, phthalates, and per- and poly-fluoroalkyl substances (PFAS) have attracted significant attention due to their prevalence and adverse effects. Accurately identifying and quantifying these EDCs is important for assessing exposure levels and evaluating the associated risks. This review article shed the light on recent advancements in modified electrochemical sensors and biosensors using nanomaterials, molecularly imprinted polymers (MIPs), Metal organic frameworks and nanocomposite-based electrodes, and their applicability for detecting EDCs during the past five years. The development of innovative electrode materials, optimization strategies used to increase the sensitivity and selectivity of electrochemical sensors. The challenges of real-world sample analysis are investigated as well along with possible solutions, such as matrix interference and detection limitations. Future perspectives and emerging trends in the electrochemical detection of EDCs, are also elaborated with a particular emphasis on developments in portable and miniaturized devices, multiplexed sensing platforms, and the incorporation of machine learning and artificial intelligence for better data analysis, and on-site detection.

“…While multiple forms of detection are available for capillary-flow microfluidic devices, electrochemical detection is particularly attractive because sensitive and quantitative results can be obtained using low-cost and portable instrumentation. [26][27][28][29][30] In our previous publications with electrochemical capillary-flow microfluidic devices, we have fabricated screen-printed electrodes in-house because they are low cost, have tunable designs, and can be printed directly on the top layer of the microfluidic device. 22,31 However, in-house electrodes require specialized materials, added time, and specialized skills and tools for fabrication.…”

“…Therefore, only a suitable choice of material could stably immobilize these biomolecules and access their active centers without damaging their secondary structures. To address this, researchers have developed various biocompatible and conductive materials in order to improve and enhance the electrocatalytic performance of these immobilized biomolecules, which include metal nanoparticles, carbon nanomaterials, organic frameworks, ionic liquids, conducting polymers, quantum dots, nanodots, etc., and still the search continues [ 37 , 38 , 39 , 40 ]. As a result, thousands of biosensor platforms are being published every year.…”

Electrochemical biosensors are superior technologies that are used to detect or sense biologically and environmentally significant analytes in a laboratory environment, or even in the form of portable handheld or wearable electronics. Recently, imprinted and implantable biosensors are emerging as point-of-care devices, which monitor the target analytes in a continuous environment and alert the intended users to anomalies. The stability and performance of the developed biosensor depend on the nature and properties of the electrode material or the platform on which the biosensor is constructed. Therefore, the biosensor platform plays an integral role in the effectiveness of the developed biosensor. Enormous effort has been dedicated to the rational design of the electrode material and to fabrication strategies for improving the performance of developed biosensors. Every year, in the search for multifarious electrode materials, thousands of new biosensor platforms are reported. Moreover, in order to construct an effectual biosensor, the researcher should familiarize themself with the sensible strategies behind electrode fabrication. Thus, we intend to shed light on various strategies and methodologies utilized in the design and fabrication of electrochemical biosensors that facilitate sensitive and selective detection of significant analytes. Furthermore, this review highlights the advantages of various electrode materials and the correlation between immobilized biomolecules and modified surfaces.
