“…Crucial to this building process is the creation of fully functional nanoscale building blocks of various sizes and shapes. 1,2 To meet this demand, various methods, such as metalorganic chemical vapor deposition (MOCVD), 3 chemical vapor deposition (CVD), 4,5 laser ablation, 6 sol-gel, 7 and thermal evaporation 8 have been successfully used to produce a variety of nanowires/ nanotubes, such as C, 9,10 Si, 11,12 SiO 2 ,4,13 and GaN 14,15 ; nanorods 16,17 ; nanobelts 18 ; and even nanorings. 19 GaN epitaxial films and devices have attracted considerable attention because of their broad applications in blue/green light emitting diodes, 20,21 laser diodes and photodetectors, 3,15 and high-power/high-temperature electronics.…”

The deformation behavior of single-crystal GaN nanowires was studied by directly performing three-point bending tests on each individual nanowire in an atomic force microscope. The elastic modulus calculated from the load-displacement response of the nanowires was 43.9 ± 2.2 GPa. Single-crystal GaN nanowires investigated in this study were synthesized by chemical vapor deposition techniques based on the vapor-liquid-solid growth mechanism and had a diameter range from 60 to 110 nm. Crystalline GaN nanowires did not show obvious plastic deformation in bending and usually failed in a brittle manner.

“…The ratio of zinc vapor pressure to oxygen vapor pressure controls the morphology of ZnO and thus induces defects in the crystal structure which, in turn, controls the electrical characteristics of the film. Due to the availability of a large number of synthesis techniques, the conditions and growth mechanism for the preparation of ZnO nanostructures vary across research groups [ 47 , 49–52 ].…”

Over the past few decades zinc oxide (ZnO)-based thin films and nanostructures have shown unprecedented performance in a wide range of applications. In particular, owing to high isoelectric point, biocompatibility and other multifunctional characteristics, ZnO has extensively been studied as a transduction material for biosensor development. The fascinating properties of ZnO help retain biological activity of the immobilized biomolecule and help in achieving enhanced sensing performance. As a consequence of recent advancements in this multidisciplinary field, diagnostic biosensors are expanding beyond traditional clinical labs to point-of-care and home settings. Label-free electrical detection of biomarkers has been demonstrated using ZnO-sensing platforms. In this review we highlight the characteristics of ZnO that enable realization of its use in development of point-of-care biosensors toward disease diagnosis, in particular cardiovascular diseases.

“…Compared with other semiconductor materials, zinc oxide has unique polar surface, and may form various nanostructures under the action of surface polarization charges and atoms with broken bond. The specific nanostructures that may be observed include tubular [6], comb-like [7], rod-like [8], ribbon-like [9] and hollow globe-like [10]. ZnO specimens…”

Using Zn(NO 3 ) 2 •6H 2 O and NaOH as raw materials, hydrothermal method was employed to prepare nano-ZnO by changing the proportion of materials and adding surfactant. The products were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that at n(OH − ):n(Zn 2+ ) = 4:1, the nano-ZnO had a sheet-like structure with average thickness of 80 nm; at (OH − ): n(Zn 2+ ) = 10:1, nano-ZnO had a pencil-like structure with the diameter of 220 nm. Rhodamine was used as pollutant to carry out photocatalytic experiments. The results indicated that the photocatalytic performance of sheet-like ZnO was superior to that of pencil-like ZnO. As to the influence of different surfactants, the ZnO had a rodlike structure with the addition of dodecyltrimethylammonium bromide (DTAB), and its photocatalytic performance was enhanced. The photocatalytic performance of ZnO prepared with the addition of Sodium dodecylbenzenesulfonate (DBS) was also improved, though by a smaller extent compared with the addition of DTAB.
