High-performance glucose biosensors are highly desired for healthcare. To meet these demands, glucose biosensors, particularly enzyme-free glucose biosensors, have received much attention. Two-dimensional materials, e.g., graphene, with high surface area, excellent electrical properties, and good biocompatibility, have been the main focus of biosensor research in the last decade. This review presents the recent progress made in enzyme-free glucose biosensors based on MoS 2 nanocomposites. Two different techniques for glucose detections are introduced, with an emphasis on electrochemical glucose biosensors. Challenges and future perspectives of MoS 2 nanocomposite glucose biosensors are also discussed.

“…The use of bimetallic NPs has greatly helped the development of electrochemical-based sensors for the detection of H 2 O 2 in biological samples, such as human cancer cells [ 198 ], human serums, and human urine [ 197 ]. Therefore, bimetallic NPs have the potential to enhance the overall sensor performance through higher conductivity, greater selectivity, and less sensor deactivation, making them more suitable for biological systems [ 199 , 200 , 201 ].…”

Reactive oxygen species (ROS) have been found in plants, mammals, and natural environmental processes. The presence of ROS in mammals has been linked to the development of severe diseases, such as diabetes, cancer, tumors, and several neurodegenerative conditions. The most common ROS involved in human health are superoxide (O2•−), hydrogen peroxide (H2O2), and hydroxyl radicals (•OH). Organic and inorganic molecules have been integrated with various methods to detect and monitor ROS for understanding the effect of their presence and concentration on diseases caused by oxidative stress. Among several techniques, fluorescence and electrochemical methods have been recently developed and employed for the detection of ROS. This literature review intends to critically discuss the development of these techniques to date, as well as their application for in vitro and in vivo ROS detection regarding free-radical-related diseases. Moreover, important insights into and further steps for using fluorescence and electrochemical methods in the detection of ROS are presented.

“…A number of bottom-up and top-down approaches including exfoliation (e.g., liquid exfoliation, ultrasonic exfoliation, and chemical exfoliation), hydrothermal/solvothermal synthesis, thermal decomposition as well as pulsed laser ablation can be used to synthesize Mo-based nanozymes (Table 1). 40,41,[53][54][55] Herein, representative methods for synthesis of Mobased nanozymes are presented. Multiple MoS 2 NSs with a few layers can be extensively produced by exfoliation of bulk MoS 2 .…”

Molybdenum (Mo), as a nontoxic and low-cost transition metal, has been employed for synthesis of various Mo-based nanomaterials with unique structures and physicochemical features to achieve various properties. Especially, bioinspired Mo-based nanomaterials show great potential for the construction of novel nanozyme catalysts due to their variable oxidation states. Overcoming drawbacks of natural enzymes, bioinspired Mo-based nanozymes not only provide effective catalytic sites or multivalent elements to mimic natural enzymes, but also present multiple functions for interfacing with various biomicroenvironments. Construction of vast Mo-based nanozymes has attracted enormous interest in biomedicine. Exogenous/endogenous stimuli enable the user to tailor the catalytic activities of Mo-based nanozymes. Additionally, tunable physicochemical properties also have a significant influence on their enzyme-like activity. In this review, we comprehensively summarize typical synthesis strategies, catalytic mechanism, and types of enzyme-like activity of the bioinspired Mo-based nanozymes. We mainly highlight desired merits of bioinspired Mobased nanozymes related to tunable enzyme-like activity, stability, and multifunctionality through regulating their physicochemical properties. Furthermore, we intend to discuss their biomedical applications in biosensing and detection, oncotherapy, and combating bacteria. Finally, current challenges and future perspectives of the Mo-based nanozymes are also proposed.
