Advancement in biosensing techniques is the topmost priority in the present era of technology as the limitations of conventional methods outweighs its advantages. Hence, design of compact, user and environmental friendly, economical, and highly-sensitive and responsive biosensors is needed. MXenes, two-dimensional layered material, have gained great attention in very little time due to their diverse properties such as enormous conductivity, meager cellular toxicity, elaborated surface chemistry, natural hydrophilicity, magnificent optoelectronic features, and the ability to form stable colloidal suspensions. These properties of MXenes categorize them as a potential material for fabrication of highly-efficient modern-world biosensors The surface functionalization of MXenes can be modified with polymerization, direct surface terminations etc. for enhancing the efficiency of biosensors developed from them. MXenes-based biosensors have been utilized in diverse fields viz. electrochemical biosensing, optical biosensing, wearable biosensing, etc. These biosensors are of prime importance for early detection of deadly diseases such as cancers of various body parts including lungs, pancreas, breast etc., and hyperglycaemia. Moreover, they play an important role for detecting environmental pollutants viz. heavy metals, nitrites, phenols etc. Hence, necessary actions can be taken on time in order to save the health and environment.

“…The amount of peroxides, defined as mill equivalents (meq), reflects the active oxygen per kilogram of oil. Edible oils produce a sour taste and may even cause food poisoning when the PV exceeds a critical value (Gotoh and Wada, 2006). Therefore, from the perspective of food quality and human health, the PV of edible oils needs to be determined.…”

Purpose In this study, an attempt has been made to collect the research that has been done on the construction and design of the H2O2 sensor. So far, many efforts have been made to quickly and sensitively determine H2O2 concentration based on different analytical principles. In this study, the importance of H2O2, its applications in various industries, especially the food industry, and the importance of measuring it with different techniques, especially portable sensors and on-site analysis, have been investigated and studied. Design/methodology/approach Hydrogen peroxide (H2O2) is a very simple molecule in nature, but due to its strong oxidizing and reducing properties, it has been widely used in the pharmaceutical, medical, environmental, mining, textile, paper, food production and chemical industries. Sensitive, rapid and continuous detection of H2O2 is of great importance in many systems for product quality control, health care, medical diagnostics, food safety and environmental protection. Findings Various methods have been developed and applied for the analysis of H2O2, such as fluorescence, colorimetry and electrochemistry, among them, the electrochemical technique due to its advantages in simple instrumentation, easy miniaturization, sensitivity and selectivity. Originality/value Monitoring the H2O2 concentration level is of practical importance for academic and industrial purposes. Edible oils are prone to oxidation during processing and storage, which may adversely affect oil quality and human health. Determination of peroxide value (PV) of edible oils is essential because PV is one of the most common quality parameters for monitoring lipid oxidation and oil quality control. The development of cheap, simple, fast, sensitive and selective H2O2 sensors is essential.

“…In this design, PEDOT:PSS acts as the transducer, HPU serves as the hydrogel matrix, and HRP functions as the specific redox enzyme for H 2 O 2 . These sensors demonstrate remarkable stability, with response times of less than 6 s, and offer a detection range spanning from 100 µM to 101.6 mM [ 317 ]. The flexibility and mechanical stability of this hydrogel-based electrochemical sensor make it well-suited for wearable applications.…”

Hydrogel-based wearable electrochemical biosensors (HWEBs) are emerging biomedical devices that have recently received immense interest. The exceptional properties of HWEBs include excellent biocompatibility with hydrophilic nature, high porosity, tailorable permeability, the capability of reliable and accurate detection of disease biomarkers, suitable device–human interface, facile adjustability, and stimuli responsive to the nanofiller materials. Although the biomimetic three-dimensional hydrogels can immobilize bioreceptors, such as enzymes and aptamers, without any loss in their activities. However, most HWEBs suffer from low mechanical strength and electrical conductivity. Many studies have been performed on emerging electroactive nanofillers, including biomacromolecules, carbon-based materials, and inorganic and organic nanomaterials, to tackle these issues. Non-conductive hydrogels and even conductive hydrogels may be modified by nanofillers, as well as redox species. All these modifications have led to the design and development of efficient nanocomposites as electrochemical biosensors. In this review, both conductive-based and non-conductive-based hydrogels derived from natural and synthetic polymers are systematically reviewed. The main synthesis methods and characterization techniques are addressed. The mechanical properties and electrochemical behavior of HWEBs are discussed in detail. Finally, the prospects and potential applications of HWEBs in biosensing, healthcare monitoring, and clinical diagnostics are highlighted.
