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.

“…TeMs with deposited nano- or microtubes (MTs) are among the promising composite functional materials with hollow nanostructures embedded in polymer templates [ 27 , 28 ]. They are successfully used in nanocatalysis [ 29 , 30 , 31 , 32 ], nanosensors [ 33 , 34 ], and radiation material science [ 35 , 36 ]. In our previous studies, silver-loaded composite TeMs were successfully investigated as efficient catalysts in hydrogen peroxide decomposition and p-nitrophenol reduction [ 37 , 38 , 39 ].…”

In this study, the use of composite track-etched membranes (TeMs) based on polyethylene terephthalate (PET) and electrolessly deposited silver microtubes (MTs) for the decomposition of toxic phenothiazine cationic dye, methylene blue (MB), under visible light was investigated. The structure and composition of the composite membranes were elucidated by scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffraction technique. Under visible light irradiation, composite membrane with embedded silver MTs (Ag/PET) displayed high photocatalytic efficiency. The effects of various parameters such as initial dye concentration, temperature, and sample exposure time on the photocatalytic degradation process were studied. The decomposition reaction of MB was found to follow the Langmuir–Hinshelwood mechanism and a pseudo-first-order kinetic model. The degradation kinetics of MB accelerated with increasing temperature and activation energy, Ea, was calculated to be 20.6 kJ/mol. The reusability of the catalyst was also investigated for 11 consecutive runs without any activation and regeneration procedures. The Ag/PET composite performed at high degradation efficiency of over 68% after 11 consecutive uses.

“…Au NSs have shown great potential in nanocatalysis where the catalytic efficiencies are size and shape-dependent [3]. Various methods have been developed to prepare different size and shaped Au NSs [4][5][6][7]. Among the different morphologies of Au, dendritic NSs have attracted great attention because of their potential applications in several fields and importance in understanding the growth mechanism.…”
