“…The as-deposited Zn metal film has highly dense, crack free, and triangular grain morphology, as observed in our previous studies. 33 varying dimensions with a PPH of 180 nm. Morphology C has completely lost the smooth spherical grain regions, and relatively elongated grains of diverse dimensions are grown as observed in Fig.…”

“…The mechanism of growth of these ZnO nanostructures has been reported earlier. 33 Briefly, when the metallic Zn films are subjected to annealing at 500 C, which is far beyond the melting point of metallic Zn, i.e., 420 C, the melting metal plays the role of reactant and catalyst simultaneously. At temperatures above the melting point of Zn, the metal forms molten liquid droplets and oxygen present in the ambient atmosphere get adsorbed on this surface.…”

The detection of secondary explosive molecules (e.g., ANTA, FOX-7, and CL-20) using Ag decorated ZnO nanostructures as surface enhanced Raman scattering (SERS) probes is demonstrated. ZnO nanostructures were grown on borosilicate glass substrates by rapid thermal oxidation of metallic Zn films at 500 °C. The oxide nanostructures, including nanosheets and nanowires, emerged over the surface of the Zn film leaving behind the metal residue. We demonstrate that SERS measurements with concentrations as low as 10 μM, of the three explosive molecules ANTA, FOX-7, and CL-20 over ZnO/Ag nanostructures, resulted in enhancement factors of ∼107, ∼107, and ∼104, respectively. These measurements validate the high sensitivity of detection of explosive molecules using Ag decorated ZnO nanostructures as SERS substrates. The Zn metal residue and conditions of annealing play an important role in determining the detection sensitivity.

“…The assembly of molecular building blocks or chemical synthesis through the vapor phase transport, electrochemical deposition, and solution-based or template-based growth are on the basis of preparation procedures. These procedures may include the vapor-solid or vapor-liquid-solid growth, chemical or physical vapor deposition, metal organic chemical vapor deposition, and the thermal oxidation of metals [21][22][23][24]. The vapor phase deposition method is mainly performed at elevated temperatures under the gas flow in a chamber [23,25].…”

Metal oxide materials have been applied in different fields due to their excellent functional properties. Metal oxides nanostructuration, preparation with the various morphologies, and their coupling with other structures enhance the unique properties of the materials and open new perspectives for their application in the food industry. Chemical gas sensors that are based on semiconducting metal oxide materials can detect the presence of toxins and volatile organic compounds that are produced in food products due to their spoilage and hazardous processes that may take place during the food aging and transportation. Metal oxide nanomaterials can be used in food processing, packaging, and the preservation industry as well. Moreover, the metal oxide-based nanocomposite structures can provide many advantageous features to the final food packaging material, such as antimicrobial activity, enzyme immobilization, oxygen scavenging, mechanical strength, increasing the stability and the shelf life of food, and securing the food against humidity, temperature, and other physiological factors. In this paper, we review the most recent achievements on the synthesis of metal oxide-based nanostructures and their applications in food quality monitoring and active and intelligent packaging.
