Abstract
In recent years, there has been a notable increase in interest in magnetic graphene oxide (MGO) due to its unique properties and potential applications in gas and biosensors. An extensive summary of the MGO synthesis techniques, such as chemical reduction, hydrothermal synthesis, and solvothermal synthesis, is given in this review article. Along with its many uses in gas and biosensors, sensitivity, selectivity, and stability of MGO are also highlighted. In addition to being a gas sensor that can identify ammonia, hydrogen sulfide, and volatile organic compounds, MGO can be used as a biosensor to identify proteins, glucose, cholesterol, and DNA. The conclusion of article discusses the future directions of the field as well as possible applications for MGO research across a range of industries.
