Functionalized Carbon Nanostructures for Wearable Biosensors

This chapter looks at the versatile field of functionalized carbon nanostructures as a basis for novel wearable biosensors in response to the increasing need for specialized sensors. Carbon-based structures have fascinated scientists and engineers for decades despite their discovery, showing their continued significance in modern technology. Gas sensors, electrochemical sensors, and biosensors of the future will be shaped by the versatility of carbon nanostructure-based sensors. Carbon nanostructures and their derivatives are emerging as promising platforms for sensing applications because of their unique electrical and chemical properties, scalability, biocompatibility, and functionalization potential. Their usefulness is further increased by their capacity to incorporate a broad range of inorganic nanostructured materials and biomolecules. By improving these variables, defect densification, which depends only on physical and chemical properties, becomes more controllable and sensor selectivity increases. Groundbreaking shift in sensor technology by applying novel materials such as functionalized carbon nanostructures will result in wearable biosensors that are reliable and extremely sensitive for the ever-changing field of electronics and smart gadgets. Novel approaches are required due to the constant evolution of wearable technology, and carbon-based nanostructures become an important component in this revolutionary journey. Carbon-based nanostructures are one of the most promising materials available for flexible sensing systems, because they provide a compromise between specificity and adaptability.
