“…Therefore, GO in nanoform is coated on fibers of two different fabrics and LBL technique is used to distribute the nanoparticles on fibers of the fabric more evenly for better shielding effect. Thus, nanostructured shielding materials can be lighter than microstructured ones, as well as providing equal radiation attenuation [38,43].…”

Exposure to ionizing radiation (IR) during diagnostic medical procedures brings certain risks, especially when experiencing recurrent exposures. The fabrication of nano-based composites, doped with different nanoparticles, have been suggested as effective shielding materials to replace conventional lead-based ones in material sciences and nanotechnology. In this study, commercially available fabrics, used to produce scrubs and gowns for clinical staff, are modified utilizing graphene oxide (GO) nanoparticles using a layer-by-layer (LBL) technique. GO was obtained from graphite through environmentally friendly technology by using a modified–improved Hummers’ method without NaNO3. Lightweight, flexible, air- and water-permeable shielding materials are produced that are wearable in all-day clinical practice. The nanoparticles are kept to a minimum at 1 wt%; however, utilizing the LBL technique they are distributed evenly along the fibers of the fabrics to achieve as much shielding effect as possible. The evaluation of samples is accomplished by simulating real-time routine clinical procedures and the radiographic programs and devices used daily. The GO-coated nanocomposite fabrics demonstrated promising results for X-ray shielding.

“…The method can be applied to synthesize several types of NPs, a recent review work presenting the synthesis of Fe 3 O 4 , Au, and Fe 3 O 4 /Au NPs [ 32 ]. Although the method has several advantages (including the reduced reaction time and controlled morphologies), the main drawback of the method is represented by the difficulties in the scale-up for industrial application and its cost effectiveness [ 33 ].…”

“…Polymeric compounds (polyvinyl alcohol, polyvinylpyrrolidone, polyethylene glycol, polymethacrylic acid, and polymethyl methacrylate) have been declared as highly effective protecting agents in the nanoparticle stabilization process [ 43 ]. However, following all the chemical methods has a common disadvantage, represented by the need for chemical reduction agents or stabilizers, which makes them not the primary choice in the search for “green” synthesis methods [ 33 ].…”

“…Chemical vapor deposition involves a chemical reaction and one or more volatile precursors. The method allows the synthesis of high-purity and homogeneous NPs but is strongly dependent on the substrate; high temperatures are necessary, and the by-products are represented by toxic gases [ 33 ]. Using this method, NPs such as TiO 2 , ZnO, NiO, CoFe 2 O 4 , etc., can be obtained [ 72 , 73 , 74 ].…”

Metallic and Metal Oxides Nanoparticles for Sensing Food Pathogens—An Overview of Recent Findings and Future Prospects

Nowadays, special importance is given to quality control and food safety. Food quality currently creates significant problems for the industry and implicitly for consumers and society. The effects materialize in economic losses, alterations of the quality and organoleptic properties of the commercial products, and, last but not least, they constitute risk factors for the consumer’s health. In this context, the development of analytical systems for the rapid determination of the sanitary quality of food products by detecting possible pathogenic microorganisms (such as Escherichia coli or Salmonella due to the important digestive disorders that they can cause in many consumers) is of major importance. Using efficient and environmentally friendly detection systems for identification of various pathogens that modify food matrices and turn them into food waste faster will also improve agri-food quality throughout the food chain. This paper reviews the use of metal nanoparticles used to obtain bio nanosensors for the purpose mentioned above. Metallic nanoparticles (Au, Ag, etc.) and their oxides can be synthesized by several methods, such as chemical, physical, physico-chemical, and biological, each bringing advantages and disadvantages in their use for developing nanosensors. In the “green chemistry” approach, a particular importance is given to the metal nanoparticles obtained by phytosynthesis. This method can lead to the development of good quality nanoparticles, at the same time being able to use secondary metabolites from vegetal wastes, as such providing a circular economy character. Considering these aspects, the use of phytosynthesized nanoparticles in other biosensing applications is also presented as a glimpse of their potential, which should be further explored.

“…Low et al [18] highlighted ultrasound-driven synthesis as a pragmatic solution to satisfy the growing demand for nanobiomaterials. Materials synthesis via such processes has improved properties and performance over the conventional approach and hence sono-nanotechnolgy has drawn attraction in the recent days.…”
