DNA‐Mediated Assembly of Carbon Nanomaterials

Abstract

Carbon nanomaterials (CNMs) have attracted extensive attentions on account of their superior electrical, mechanical, optical, and biological properties. However, the dimensional limit and irregular arrangement have hampered their further application. It is necessary to find an easy, efficient and controllable way to assemble CNMs into well‐ordered array. DNA nanotechnology, owning to the advantages of precise programmability, highly structural predictability and spatial addressability, has been widely applied in the assembly of CNMs. Summarizing the progress and achievements in this field will be of great value to related studies. Herein, based on the different dimensions of CNMs containing 0‐dimensional (0D) carbon dots (CDs), fullerenes, 1‐dimensional (1D) carbon nanotubes (CNTs) and 2‐dimensional (2D) graphene, we introduced the conjugation strategies between DNA and CNMs, their different assembly methods and their applications. In addition, we also discuss the existing challenges and future opportunities in the field.

Recent Advances in the DNA-Mediated Multi-Mode Analytical Methods for Biological Samples

“…Nowadays, DNA is regarded as a masterpiece in the field of nanotechnology for the multifarious and programmable structures at the nanoscale [1]. Except for the basic biological carrying functions, DNA plays the prominent role as a functional chemical molecule in the synthesis, modification and assembly of nanomaterials due to the unique properties of diverse structures, easy labeling, nanoscale rigidity, specific molecule binding and metal-ion response [2][3][4]. Thus, DNA-mediated technology driven by DNA with a specific sequence or structure can be applied in different sensing analyses to achieve selective response to the targets via various nucleic acid chain reactions [5][6][7][8] due to its distinctive properties of precise programmability, easy synthesis and high stability.…”
