Electronic Properties Of Carbon Nanotubes And Their Applications In Electrochemical Sensors And Biosensors

Abstract

Carbon nanotubes (CNTs) are a one-dimensional allotrope of graphene. Sheets of graphene are "rolled" into tubes to form well-ordered, hollow graphitic CNTs. CNTs have attracted intense interest, including in sensors and biosensors, due to their important properties, such as increased electrode surface area, fast electron transfer rate, significant mechanical strength, and good chemical stability. CNTs' unique combination of mechanical, thermal, and electrical properties make CNT fibers or CNT threads and yarns even better candidates for multifunctional materials. Apart from good electrical and mechanical properties, CNT fibers inherit the advantages of high surface area and good electrocatalytic properties of CNTs, while avoiding the potential toxicity caused by individual CNTs in the form of small particles with a high aspect ratio. Thus, CNT fibers have great potential for sensing applications. In this chapter, CNT fibers are compared with carbon fibers, a common material used for biosensing, in their applications in biosening.
