In the last 30 years, there have been increasingly developments in the fabrication, properties, and applications of graphene-based three-dimensional (3D) materials with their excellent performances of high mechanical strength, excellent surface area, high electrical conductivity, and thermal stability. Over the last century, the number of various applications of 3D graphene has increased dramatically in areas such as sensors, batteries, separation, aerospace, catalysis, and thermal management. In this chapter, all aspects of fabrication strategies, characterization, and biosensing mechanisms of 3D graphene-based biosensors are reviewed. In addition, there is a great deal of interest in a variety of 3D graphene-based sensor systems, such as gas sensors, health monitoring, wearable temperature sensors, electrochemical food sensors, and environmental pollutant sensors. Consequently, a comprehensive understanding of the unique performance, current limitations, and outlook of 3D graphene-based biosensors was highlighted.
