Special Issue Information

Dear Colleagues,

This Special Issue will deal with the nano-technological aspects of devices for the development of selective portable sensor probes with doped or undoped low-dimensional nanostructure metal oxides or composite materials on substrates. Low-dimensional metal oxides have been developed for a variety of sensor applications, ranging from chemicals to biochemicals for the safety of the environmental and healthcare fields. This Special Issue will also focus on a particular field of sensor applications of doped and undoped nanostructure and nanocomposite materials as sensor devices, systems, or strategies. This Special Issue aims to publish state-of-the-art original articles and comprehensive reviews covering nanostructure/nanocomposite-based chemical and biosensors from the design, fabrication, chemistry, analysis, investigation, and/or applications perspectives. Although the emphasis is on practical applications, fundamental concept and practical studies are also welcome. I hope that this selective Special Issue has certainly attained the achievement of its essential aim and achieved innovative routes of preparation, improvement, and continuous changes with multiple dimensions in the nano- and bio-technological areas. It will focus on cutting-edge nano-sciences and bio-technology of nanocomposite and nanostructure metal oxides. It is expected to guide the preparation of novel doped or undoped materials with special properties, functions, characterization, and potential applications. It will open up bright possibilities for the solution to environmental, biomedical, and ecological problems. I hope that this Special Issue will contribute to bequeathing an attractive atmosphere and precious resources to subsequent generations.

Here, a sensitive voltametric electrochemical sensor probe was fabricated to reliably trace the detection of L-aspartic acid in phosphate-buffered medium using a glassy carbon electrode (GCE) layered with a film of wet-chemically prepared Ag2O-doped ZnO nanosheets (NSs). EDS, FESEM, XPS, and X-ray diffraction analyses were implemented as characterizing tools of prepared NSs to confirm the structural and compositional morphology, binding energies of existing atoms, and the crystallinity of synthesized NSs. The differential pulse voltammetry (DPV) was applied to the trace detection of L-aspartic acid, and exhibited a wide detection range of 15.0~105.0 µM, a limit of detection (3.5 ± 0.15 µM), and good sensitivity (0.2689 µA µM−1 cm−2). Besides these the precious reproducibility, stability, and efficient responses were perceived from the voltametric analysis of aspartic acid. Moreover, the proposed aspartic acid was subjected to experiments to potentially detect aspartic acid in real biological samples. Therefore, the development of an enzyme-free sensor by applying this method will be a smart technical approach in the near future. Full article
