“…56 The 3-D ZnO Preparation based on Solution Approach Different from other ZnO dimensional nanostructures, the synthesis methods of 3-D ZnO are quite limited. Several method have been developed to synthesize the nanoparticles, 57 nanorods, 58 nanotubes, 59 nanowires, 60 nanosheets, 61 and nanoflakes 62 based on various techniques approaches such as vapour, solid, and solution. However, from the literature survey, solution approach is often used to synthesize 3-D ZnO because it can allows the self-assembly of the heterostructures or hybrid nanomaterials cost-effectively.…”

Morphology effect is one of the essential factors that influence the performance of electrochemical biosensors based on ZnO nanostructures. These nanostructures are characterized by anisotropic growth with different dimensionalities such as zero-dimensional, one-dimensional, and two-dimensional. More interestingly, when combining each dimension into another advanced dimensionality, i.e. the three-dimensional (3-D), exceptional properties can be generated that are not otherwise found in low dimensionalities. The outstanding popularity of 3-D ZnO stems from many factors, with one of the most important being its synergic advantages from its low dimensional sub-unit and the additional surface area of the 3-D structure due to an increased geometric volume. This review briefly describes the principles and growth mechanism factors of 3-D ZnO via solution-based approaches and additional advanced methods. The paper further expands on the latest advancement of research into the 3-D ZnO nanostructure-based electrochemical biosensors to detect biomolecules that harm humankind. We also discussed the analytical performance of these biosensors using different nanocomposite materials. Additionally, limitations and suggestions on particular sensing works are proposed. Lastly, the five-year progress in research into 3-D ZnO-based electrochemical biosensors’ performance in healthcare diagnosis is compared and future challenges presented.

ZnO films were deposited on two substrates Silicon (Si) and glass using RF magnetron sputtering. Our aim is to characterize the structural and the nonlinear optical (NLO) properties of the new ZnO films. Both of XRD and EDX analysis were utilized to reveal some information about the structural improvements and composition of our new films. Also, morphology and thickness of the films have been acquired from a scanning electron microscope (SEM). The nonlinear absorption (NLA) coefficients of the new films were estimated from the experimental data. Our observations suggest that the present grains on the films surface could be as clusters of crystallites. The optical band gaps (Eg) of the new ZnO prepared films were found about 3.25 eV for film thickness of 500 nm and 3.29 eV for the other film thickness of 1200 nm. It was found that the two films thickness have a good quality with (002) prefer orientation, as well as compared with (002) single crystal ZnO using z-scan method. The NLA coefficient (β) of the film is inversely proportional with the films thickness.

ZnS film has been deposited on PbS buffer layer using thermal evaporation, the ZnS film has nanostructure (nanowires) due to effect of PbS which play role of catalyst. This growth for non doped films have dense structure (for PbS and ZnS films). SEM morphology of ZnS/PbS, ZnS and PbS have been studied in details (surface and cross section). Atomic force microscopy (AFM) used to characterized the thins films (ZnS and PbS). X-ray photoelectron spectroscopy (XPS) and EDX techniques have utilized to know the chemical and stoichiometry of deposited films. The crystallographic properties have been studied using XRD patterns, it found that the results in Raman and XRD characterization have a good agreement. UV-Vis spectroscopy is used to acquire an idea about optical properties of thin films deposited on glass substrate. The deposited ZnS nanowires and thin film have hexagonal phase, which indicate to the buffer layer, which does not affects the structural but changes the growth mechanism. High Resolution Transmission Electron Microscope (HRTEM) images have confirmed the formation of ZnS nanowires..
