The imbalance in generation of reactive oxygen species and its depletion causes oxidative stress. Because of its importance, there is a need to explore the role of oxidative stress biomarkers. The limitations of the conventional methods cause the researchers look for other alternatives. Biosensors are highly promising candidates for the detection of trace quantities for various analytes with high specificity, selectivity, and quick response time. Nanomaterial based matrices are the most popular choice while fabricating a biosensor. Two-dimensional (2D) materials such as graphene, transitional metal dichalcogenides, and various metal oxides have been used for the biosensing of different oxidative stress analytes. High electron mobility, good optical properties, tunable properties, high yields, easy synthesis, and availability make these materials the first choice. In this review, we have comprehensively discussed various biomarkers associated with oxidative stress. The review will provide information related to different kinds and various synthesis procedures employed for 2D nanomaterials. The major focus of the review is to elaborate the role of 2D nanomaterial based structures for the optical and electrochemical methods for the detection of oxidative stress. This review is an effort to help the researchers better understand various 2D based transducers available for the detection of oxidative stress biomarkers.

Sulfur doping in carbonaceous materials is an effective approach to improve the performance of Li‐ion batteries (LIBs). Herein, sulfur‐implanted carbon dots‐embedded graphene (S‐CDs/rGO) as an anode material for LIBs is reported. A facile method is used to prepare S‐CDs/rGO by annealing the mixture of benzyl disulfide (BDS) and graphene oxide (GO). Herein, BDS serves as both the sulfur source and precursor of CDs. S‐CDs/rGO as an anode material for LIB delivers initial specific capacities of 938.8 mAh g−1 (first cycle) and 598.6 mAh g−1 (second cycle) at a current density of 100 mA g−1. S‐CDs/rGO exhibits superior cycling performance with good capacity retentions of 78.8% (500 cycles), 61.5% (2000 cycles), and 75.7% (2000 cycles) at higher current densities of 1000, 2000, and 3000 mA g−1, respectively. Moreover, the full cell assembly of the prepared S‐CDs/rGO as an anode and commercial LiFePO4 as a cathode in the voltage range of 1.5–3.9 V delivers a high reversible capacity of 203.3 mAh g−1 after extensive 1000 cycles at 500 mA g−1 with 51.8% retention (a low fading rate of 0.049% per cycle), rendering it as a promising anode material for application in high‐performance LIBs.
