“…SWNT diodes exhibit excellent power conversion efficiencies when illuminated, due to improved diode properties [194]. Non-covalent doping can tune the doping type and degree of the SWNT without producing structure defects [195]. The diameter of SWCNT can be used to control its energy gap to produce the p-n junction diodes with different characteristics [196].…”

Carbon nanotubes (CNTs) are known as nano-architectured allotropes of carbon, having graphene sheets that are wrapped forming a cylindrical shape. Rolling of graphene sheets in different ways makes CNTs either metals or narrow-band semiconductors. Over the years, researchers have devoted much attention to understanding the intriguing properties CNTs. They exhibit some unusual properties like a high degree of stiffness, a large length-to-diameter ratio, and exceptional resilience, and for this reason, they are used in a variety of applications. These properties can be manipulated by controlling the diameter, chirality, wall nature, and length of CNTs which are in turn, synthesis procedure-dependent. In this review article, various synthesis methods for the production of CNTs are thoroughly elaborated. Several characterization methods are also described in the paper. The applications of CNTs in various technologically important fields are discussed in detail. Finally, future prospects of CNTs are outlined in view of their commercial applications.

“…First-principles studies on the interaction of conjugated polymers with (8, 0) SWCNT and (10 × 10) graphene sheet was investigated by Jilili et al [69], to confirm the experimental observation that polymers are suitable for noncovalent functionalization. The GGA approximation was predicted to be inadequate in describing the physisorbed systems, whereas LDA and vdW corrected GGA yield conclusive results.…”

Carbon nanotubes (CNTs) have attracted substantial research interest in biomedical sciences and bionanotechnology, rendered from its unique structure, electronic, mechanical, and optical properties. Despite the diverse potential applications, the integration of CNTs in biomedical research is one of the most challenging areas where nanotubes fall under much scrutiny. Pristine nanotubes are highly hydrophobic, and non-dispersible in most of the common aqueous and organic solvents and to render nanotubes biocompatible, functionalization is one of the key prerequisites. In this regard, covalent and noncovalent functionalization are the two widely adopted approaches for co-tethering biologically active molecules on the CNTs. Likewise, the hollow cavity of the nanotube facilitates in the endohedral encapsulation of biomolecules, peptides, DNA oligonucleotides, and proteins, thereby retaining the physiological attributes of the biological molecules. The chapter focuses on the emerging approaches to the functionalization of single-wall CNTs (SWCNTs) and the potential application of functionalized SWCNTs in tuberculosis and cancer chemotherapy using state-of-the-art density functional theory, molecular docking and molecular dynamics simulation methods. means 'to write'. Graphene an acronym for the 2D layered graphite, is the mother of all carbon materials [1], as a graphene sheet can be wrapped to form 0D fullerenes, rolled to form 1D nanotubes, or stacked to form 3D graphite as depicted in Figure 1. The unearthing of "groundbreaking experiments regarding the two-dimensional material graphene" by Geim and Novoselov in 2010, heralded graphene as the next generation carbon material [2].CNTs are hexagonally arranged, honey-combed lattice of carbon atoms formed by the rolling of graphene into seamless cylindrical structures (see Figure 2a). Nanotubes like graphene have a high diameter to length ratio (aspect ratio) [3] and demonstrate high electrical, mechanical, and thermal conductivity along with structural stability [4][5][6][7]. CNTs are broadly classified as single-wall CNTs (SWCNTs) and multi-wall CNTs (MWCNTs). The SWCNT comprise of a single graphene sheet, with diameter ~ 0.5-1.5 nm and length of ~100 μm [8], while MWCNT is formed from the co-axial stacking of SWCNTs, with diameter ~1.4-100 nm, length between 1 nm-μm, and internuclear distance of 0.3-0.4 nm between the co-axial tubes. The representation of a zigzag (m = 0), armchair (n = m), and chiral (n ≠ m) nanotube is depicted in Figure 2b-d.The (n, m) indices render remarkable electronic properties to the CNTs [9] and the sp 2 hybridization along the tubular axis makes it chemically inert by nature.

“…Unfortunately, graphene has a tendency to aggregate in most solvents because of the van der Waals between the graphene layers, which restricting the efficient applications of graphene over a large scale [5]. In order to overcome the limit, intensive research has been devoted to the modification of graphene by covalent [6,7] and non-covalent [8,9] methods. However, covalent linkage usually leaves some sp 3 carbons in graphene which will result in the damage of electrochemical properties of graphene.…”
