Sensors continue to make significant impact in everyday life. There has been a strong demand for producing highly selective, sensitive, responsive, and cost effective sensors. As a result, research emphasis is on developing new sensing materials and technologies. Carbon nanotubes (CNTs) have many distinct properties that may be exploited to develop next generation of sensors. This manuscript reviews the distinct physical, electronic, and mechanical properties of CNTs. The main thrust of this review is to highlight the present and future research and development work in the area of carbon nanotube sensors for real-world applications. The technical challenges associated with CNT-based sensors, which remain to be fully addressed, have also been outlined at the end of the manuscript. This review aims to act as a reference source for researchers to help them in developing new applications of CNT-based sensors.

“…6. The temporal conductance variation has been applied to the detection of bacteria (Suehiro et al 1999) as well as to monitoring and controlling CNTs trapping process for CNT sensor fabrication (Suehiro et al 2005). A SEM image obtained for mixture of bacteria and MWCNTs is shown in Fig.…”

“…The present authors have demonstrated that the DEP manipulation could provide a way to trap biological cells (Suehiro et al 1999(Suehiro et al , 2003a, CNTs (Suehiro et al 2003c(Suehiro et al , 2005(Suehiro et al , 2006a, carbon nanohorns (Suehiro et al 2006b), zinc oxide (ZnO) nanowires (Suehiro et al 2006c) and palladium (Pd) nanoparticles ) on a microelectrode. One advantage of the DEP manipulation technique is that one can quantify the amount of trapped cells or nanomaterials on a real time basis by monitoring electrical impedance of the microelectrode (dielectrophoretic impedance measurement, DEPIM) (Suehiro et al 1999(Suehiro et al , 2003a.…”

The authors have previously demonstrated the manipulation of bacteria and carbon nanotubes (CNTs) using dielectrophoresis (DEP) and its application for various types of biological and chemical sensors. This paper demonstrates simultaneous DEP handling of bacteria and CNTs, which are mixed and suspended in water. The CNTs were solubilized in water using microplasma-based treatment. When a microelectrode was energized with an ac voltage in the suspension of Escherichia coli (E. coli) cells and multi-walled CNTs (MWCNTs), both of them were simultaneously trapped in the microelectrode gap. Scanning electron microscopy (SEM) images revealed that E. coli cells were trapped on the surface or the tip of MWCNTs, where the electric field strength was intensified due to high aspect ratio of MWCNTs. As a result, bio/nano interfaces between bacteria and MWCNTs were automatically formed in a self-assembly manner. A potential application of the DEP-fabricated bio/nano interfaces is a drug delivery system (DDS), which is realized by transporting drug molecules from CNTs to cells across the cell membrane, which can be electroporated by the local high electric field formed on the CNT surface.
