Recent progress in the combination of nucleic acids and carbon nanotubes (CNTs) has been briefly reviewed here. Since discovering the hybridization phenomenon of DNA molecules and CNTs in 2003, a large amount of fundamental and applied research has been carried out. Among thousands of papers published since 2003, approximately 240 papers focused on biological applications were selected and categorized based on the types of nucleic acids used, but not the types of CNTs. This survey revealed that the hybridization phenomenon is strongly affected by various factors, such as DNA sequences, and for this reason, fundamental studies on the hybridization phenomenon are important. Additionally, many research groups have proposed numerous practical applications, such as nanobiosensors. The goal of this review is to provide perspective on biological applications using hybrids of nucleic acids and CNTs.

“…It should be noted that graphene is also an appropriate support for the immobilization of pyrene-modified oligonucleotide probes. Zhang et al designed graphene-coated gold electrode and functionalized it with 1-pyrenebutanoic acid N -oxysuccinimide ester, followed by the grafting of the 5′-amino-modified oligonucleotide probe [ 260 ]. Cyclic voltammetry and electron impedance spectroscopy demonstrated high sensitivity of the biosensor towards complementary target in the presence of the electroactive indicators, methylene blue, or [Fe(CN) 6 ] 3−/4− (the limit of detection was 380 aM).…”

Recent Advances in Nucleic Acid Targeting Probes and Supramolecular Constructs Based on Pyrene-Modified Oligonucleotides

et al. 2017

In this review, we summarize the recent advances in the use of pyrene-modified oligonucleotides as a platform for functional nucleic acid-based constructs. Pyrene is of special interest for the development of nucleic acid-based tools due to its unique fluorescent properties (sensitivity of fluorescence to the microenvironment, ability to form excimers and exciplexes, long fluorescence lifetime, high quantum yield), ability to intercalate into the nucleic acid duplex, to act as a π-π-stacking (including anchoring) moiety, and others. These properties of pyrene have been used to construct novel sensitive fluorescent probes for the sequence-specific detection of nucleic acids and the discrimination of single nucleotide polymorphisms (SNPs), aptamer-based biosensors, agents for binding of double-stranded DNAs, and building blocks for supramolecular complexes. Special attention is paid to the influence of the design of pyrene-modified oligonucleotides on their properties, i.e., the structure-function relationships. The perspectives for the applications of pyrene-modified oligonucleotides in biomolecular studies, diagnostics, and nanotechnology are discussed.

“…In the recent years, it has been reported that constructing noncovalent bond interactions at the interfaces of inorganic filler and elastomer can improve the strength and toughness of materials at the same time. The strength of noncovalent secondary bonds, such as van der Waals force (including hydrogen bond), π‐π conjugate interactions, π‐cation interactions and ionic bonds, is weak, but through multiple layers, a large number of reasonable matching can also achieve interfacial load transfer and strength increase. More importantly, this secondary bond can dissipate the additional strain energy through the shedding and fracture during the strain process, thus ensure the toughness and ductility of the materials.…”

“…The strength and toughness of rubber could be improved at the same time. In addition, Zhang constructed π‐π conjugation interaction in graphene sheets using 1‐pyrenebutyric acid as modifier, and indirectly estimated that the binding energy of pyrene derivatives with graphite sheets was about 26 kJ/mol by single molecular force microscopy. Li also showed that the dissociation energy of hydrogen bonds in polyurethane was approximately 16.7 kJ/mol by system infrared measurements.…”

The surface modification of graphene oxide was carried out with dodecylbenzene, and the π‐π noncovalent interaction was introduced between the interfaces of graphene oxide and dodecylbenzene. The modified graphene oxide was added to ethylene‐propylene‐diene monomer by mechanical blending, and then the ethylene‐propylene‐diene monomer/modified graphene oxide vulcanizate was prepared. The results show that the dodecylbenzene loading rate on the surface of graphene oxide was about 40%. The addition of the graphene oxide and the modified graphene oxide was both beneficial to improve the thermal stability of the ethylene‐propylene‐diene monomer, but the effect of the modified graphene oxide was better. The addition of graphene oxide would cause the glass transition temperature of vulcanizate to shift toward higher temperature. However, the addition of modified graphene oxide would result in the glass transition temperature of vulcanizate to shift toward lower temperature. The tensile strength and elongation at break of vulcanizate would be improved simultaneously with the addition of modified graphene oxide. The reason was related to the slipping of dodecylbenzene on the surface of graphene oxide and the destruction of π‐π non‐covalent bonds at dodecylbenzene‐graphene oxide interfaces. © 2019 Wiley Periodicals, Inc.
