“…The XRD pattern exhibited out-of-plane X-ray diffractograms (theta-2 theta geometry) of the nonannealed and annealed ZnO/Al 2 O 3 core-shell nanowire structures (as illustrated in Figure 3 i,j). For the nonannealed one, the diffracting patterns at ~34.45° and ~47.58° were attributed to (002) and (102) planes of the hydrothermal ZnO nanowire with the hexagonal wurtzite structure [ 24 ]. The predominant intensity of (002) plane strongly suggested that ZnO nanowire hydrothermally grew on the substrate surface with the preferential orientation along [0001] direction (c-axis) [ 25 ].…”

RNA analytical platforms gained extensive attention recently for RNA-based molecular analysis. However, the major challenge for analyzing RNAs is their low concentration in blood plasma samples, hindering the use of RNAs for diagnostics. Platforms that can enrich RNAs are essential to enhance molecular detection. Here, we developed the annealed ZnO/Al2O3 core-shell nanowire device as a platform to capture RNAs. We showed that the annealed ZnO/Al2O3 core-shell nanowire could capture RNAs with high efficiency compared to that of other circulating nucleic acids, including genomic DNA (gDNA) and cell-free DNA (cfDNA). Moreover, the nanowire was considered to be biocompatible with blood plasma samples due to the crystalline structure of the Al2O3 shell which serves as a protective layer to prevent nanowire degradation. Our developed device has the potential to be a platform for RNA-based extraction and detection.

“…Details of high-quality vertically aligned ZnO NRs arrays formation on seeded indium tin oxide (ITO, 20 ohm/sq) glass have been reported in previous work. 22 To develop a ZnO NRs/CdS heterostructure, the ITO/ZnO NR photoanode was first dipped in 0.16 M cadmium acetate dihydrate (Cd(CH 3 COO) 2 ·2H 2 O, purity 98%, Merck, CAS no. 5743-04-4) ethanolic solution for 30 s to allow the adsorption of Cd 2+ ions, followed by rinsing for 30 s using methanol (CH 3 OH, AR grade, Chemiz, CAS no.…”

“…Several methods have been described for producing well-aligned ZnO nanorods from aqueous solutions. Conventionally, an aqueous solution is prepared for the growth of ZnO nanorods by dissolving a certain molar ratio of zinc nitrate hexahydrate

together with hexamethylene tetraamine (HMTA) [ 91 , 92 , 93 ]. This synthetic pathway and its modifications have been widely used to improve the orientation, crystallinity, diameter, and aspect ratio of nanorods.…”

Zinc oxide (ZnO) nanorods have attracted considerable attention in recent years owing to their piezoelectric properties and potential applications in energy harvesting, sensing, and nanogenerators. Piezoelectric energy harvesting-based nanogenerators have emerged as promising new devices capable of converting mechanical energy into electric energy via nanoscale characterizations such as piezoresponse force microscopy (PFM). This technique was used to study the piezoresponse generated when an electric field was applied to the nanorods using a PFM probe. However, this work focuses on intensive studies that have been reported on the synthesis of ZnO nanostructures with controlled morphologies and their subsequent influence on piezoelectric nanogenerators. It is important to note that the diatomic nature of zinc oxide as a potential solid semiconductor and its electromechanical influence are the two main phenomena that drive the mechanism of any piezoelectric device. The results of our findings confirm that the performance of piezoelectric devices can be significantly improved by controlling the morphology and initial growth conditions of ZnO nanorods, particularly in terms of the magnitude of the piezoelectric coefficient factor (d33). Moreover, from this review, a proposed facile synthesis of ZnO nanorods, suitably produced to improve coupling and switchable polarization in piezoelectric devices, has been reported.
