Special Issue Information

Dear Colleagues,

The area of nanomaterials functionalization opens a new platform for modern scientific innovation and novel device fabrication in analytical sciences. Functionalized nanomaterials reformulate new materials with advanced characteristics for improved applications in comparison to old-fashioned materials, and provide numerous opportunities for the developments of new devices and new techniques with a direct impact on health and sustainability. The interest in accessing the complex information leads to develop new methods (device development) and analytical techniques.
As a smart transducer, functionalized nanomaterials play a critical role in developing high throughput analytical devices/platforms. Role of functionalized nanomaterials are not only limited to the field of chemo- and bio-sensor, however, these materials are also receiving increasing importance towards fabrication of sensing interfaces and devices for other application domains ranging from food quality analysis to environmental and biomedical applications. Moreover, these materials have a high level of potency for wide applications penetrating through all the discipline of knowledge, leading to industrial and technological evolution.
We are pleased to announce the Special Issue on sensing application of functionalized nanomaterials. This SpecialIssue will cover both theoretical and experiments studies on application of functionalized nanomaterials in developing devices/platform for chemo- and -bio sensing of range of disease biomarkers, pathogens, environmental pollutants, food analysis and in other biomedical applications.
On behalf of the Guest Editors, we encourage you to submit your recent research work, critical/tutorial review and short focus articles to provide snapshots of research for a wider audience, in this particular issue on functionalized nanomaterials for sensing applications.

In this paper, silver-doped zinc oxide nanoparticles were synthesized by using a solution combustion technique, in which zinc nitrate is used as an oxidizer and tartaric acid as a fuel. The phase composition, morphology and structural properties of the as-synthesized zinc oxide and silver-doped zinc oxide were established by using powdered X-ray diffraction, field emission scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy studies. Due to well-defined morphologies and crystallinity, the pure zinc oxide and silver-doped zinc oxide nanostructures can be used as efficient chemical sensors for the detection of p-nitrophenol (PNP). ZnO was found to show a low value of the limit of detection (LOD), i.e., 2.175 µM/L, for p-nitrophenol sensing; moreover, a sharp decrease in the limit of detection was observed with an increase in the concentration of silver ions, and the LOD value decreased to 0.669 µM/L for 10 mol % silver-doped zinc oxide. It is therefore concluded that Ag-doped ZnO shows a lower limit of detection as compared to pure ZnO for p-nitrophenol sensing. Full article

The early detection of Legionella in water reservoirs, and the prevention of their often fatal diseases, requires the development of rapid and reliable detection processes. A method for the magnetic separation (MS) of Legionella pneumophila by superparamagnetic iron oxide nanoparticles is developed, which represents the basis for future bacteria detection kits. The focus lies on the separation process and the simplicity of using magnetic nanomaterials. Iron oxide nanoparticles are functionalized with epoxy groups and Legionella-specific antibodies are immobilized. The resulting complexes are characterized with infrared spectroscopy and tested for the specific separation and enrichment of the selected microorganisms. The cell-particle complexes can be isolated in a magnetic field and detected with conventional methods such as fluorescence detection. A nonspecific enrichment of bacteria is also possible by using bare iron oxide nanoparticles (BIONs), which we used as a reference to the nanoparticles with immobilized antibodies. Furthermore, the immunomagnetic separation can be applied for the detection of multiple other microorganisms and thus might pave the way for simpler bacterial diagnosis. Full article

Integration of materials acts as a bridge between the electronic and biological worlds, which has revolutionized the development of bioelectronic devices. This review highlights the rapidly emerging field of switchable interface and its bioelectronics applications. This review article highlights the role and importance of two-dimensional (2D) materials, especially graphene, in the field of bioelectronics. Because of the excellent electrical, optical, and mechanical properties graphene have promising application in the field of bioelectronics. The easy integration, biocompatibility, mechanical flexibility, and conformity add impact in its use for the fabrication of bioelectronic devices. In addition, the switchable behavior of this material adds an impact on the study of natural biochemical processes. In general, the behavior of the interfacial materials can be tuned with modest changes in the bioelectronics interface systems. It is also believed that switchable behavior of materials responds to a major change at the nanoscale level by regulating the behavior of the stimuli-responsive interface architecture. Full article
