“…In addition, passivation treatment by depositing a HfO 2 layer can alleviate the degradation of NWs exposed to aqueous solutions, which will produce a conductivity response similar to the negative charge signals. Recently, chemical resistance biosensors based on semiconductor SWCNTs (sc-SWCNTs) and nitrogen-doped MWCNTs (N-MWCNTs) have been compared for DNA sequencing derived from avian influenza virus H5N1 ( Figure 10 ) [ 103 ]. The relatively higher sensitivity to the DNA target sequence was found in sc-SWCNTs with the lowest detection concentration down to 2 pm (20 pm in N-MWCNTs).…”

Since the first introduction of one-dimensional nanochannels for single-molecule detection, there has been increasing interest in modern nanofluidic systems, such as chemical and biological sensing applications. Recently developed nanowires (NWs) and nanotubes (NTs) have received tremendous attention due to their unique geometrical, physical and chemical properties, which are very attractive in this field. Here, we review the recent research activities in the field of novel nanofluidic cells based on NWs and NTs. First, we give a brief introduction of this field. Then the common synthesis methods of NWs and NTs are summarized. After that, we discuss the working principle and sensing mechanism of nanofluidic devices, which is fundamental to the interaction between these nanostructures and small molecules. Finally, we present the NW- and NT-based devices for chemical and bio-sensing applications, such as gas sensing, pathogen detection, DNA sequencing, and so forth.

“…Fu et al [131] developed chemiresistive biosensor based on carbon nanotubes for detecting avian influenza virus H5N1. In these sensors, long nanotubes (>5 _m) were placed between the inter-digitised metal electrodes such that individual nanotubes connect the electrodes and nanotubes were functionalized with DNA probe sequences non-covalently attached to the sidewalls.…”

Single-walled carbon nanotubes (SWCNTs) exhibit outstanding properties that make them appealing in a wide range of applications. However, their properties are variable depending on the tube helicity (chirality), which has been a challenge for a long time and needs to be effectively controlled. In recent years, tremendous efforts have been made to control the electrical type/chirality of nanotubes through both direct controlled synthesis and postsynthesis separation methods. Driven by these breakthroughs, the applications of separated families of SWCNTs in various fields have emerged as a new topic of research. In this Review, an overview of recent advances in the use of highly purified and well-separated SWCNTs in a comprehensive range of applications is presented including photovoltaics, transistors, batteries, sensors, light emitters, biological/medical fields, and others. Finally, important future directions for the utilization of separated SWCNTs in these fields are provided.
