Carbon nanotubes and graphene for photonic applications

10. Carbon nanotube-based optical platforms for biomolecular detection

By: J. Pan,T.-G. Cha,H. Chen,J.H. Choi

Carbon nanotubes are exceptionally photostable fluorophores that emit in the near infrared range. Their novel optical properties make them particularly appealing for applications in biosensing. This chapter focuses on the state-of-the-art development of optical biosensors based on single-walled carbon nanotubes (SWCNTs); also, it draws attention to the basic photophysics of SWCNTs, optical-sensing mechanisms, and surface functionalization principles. The concerted efforts from the research community in the past decade have enabled the realization of several SWCNT-based optical biosensors that provide real-time, non-invasive analyte detection. We review the performance of these biosensors with regard to their sensitivity, selectivity and response time, and highlight the prospects and challenges of constructing biosensors for more advanced sensing applications.

Carbon nanotubes and graphene for photonic applications

9. Carbon nanotube solar cells

By: B.A. Baker,H. Zhang,T.-G. Cha,J.H. Choi

Carbon nanotubes have been explored in light-harvesting and photovoltaic devices because of their unique optoelectronic properties. This chapter provides a brief description of the optoelectronic properties of carbon nanotubes, particularly single-wall carbon nanotubes (SWCNTs), and their implication in various solar cell applications including donor–acceptor solar cells, polymer solar cells, and dye-sensitized solar cells, where carbon nanotubes are utilized as photoactive materials. Carbon-nanotube-based electrodes in photovoltaic devices are also introduced. Carbon-nanotube-based light-harvesting devices are reviewed in terms of fabrication and material processing as well as performance. Finally, advanced emerging methods and the future outlook for carbon-nanotube-based solar cells are discussed.
