Special Issue Information

Dear Colleagues,

This Special Issue of the journals Sensors entitled “The Applications of Nanomaterials-Based Sensors” will cover a selection of recent research and review articles in the field of nanomaterials-based sensors for several applications.

Nanomaterials offer great opportunities to develop nanomaterials-based sensors or devices for monitoring several compounds of interest in different applications, such as health, medicine, food, agriculture and crop production, energy and environment applications (in air, water and/or soil), and industry, among others.

Various nanomaterials, such as carbon nanotubes, gold nanoparticles, silicon nanowires, silica materials, and quantum dots, have been extensively explored in detecting and measuring disease biomarkers, cytotoxic, pathogens, crop diseases and growth, nutrient efficiency, toxins, toxic metal ions, toxic gases, pesticides and herbicides, hazardous industrial chemicals, and others, with high sensitivity, selectivity, and simplicity.

The use of materials at the nanodimension scale provides several improvements in terms of analytical features including sensitivity, rapidity of response, selectivity, and robustness, demonstrating the huge advantage of using nanomaterials over micromaterials in the development of smart and high-performant analytical tools.

Research on the design and development of new nanomaterials-based sensors and applications will bring together stakeholders from different disciplines. The reader of this Special Issue will gain an appreciation of the real role of nanomaterials-based sensors and applications.

The elevated concentrations of various trace metals beyond existing guideline recommendations in water bodies have promoted research on the development of various electrochemical nanosensors for the trace metals’ early detection. Inspired by the exciting physical and chemical properties of nanomaterials, advanced functional nanocomposites with improved sensitivity, sensitivity and stability, amongst other performance parameters, have been synthesized, characterized, and applied on the detection of various trace metals in water matrices. Nanocomposites have been perceived as a solution to address a critical challenge of distinct nanomaterials that are limited by agglomerations, structure stacking leading to aggregations, low conductivity, and limited porous structure for electrolyte access, amongst others. In the past few years, much effort has been dedicated to the development of various nanocomposites such as; electrochemical nanosensors for the detection of trace metals in water matrices. Herein, the recent progress on the development of nanocomposites classified according to their structure as carbon nanocomposites, metallic nanocomposites, and metal oxide/hydroxide nanocomposites is summarized, alongside their application as electrochemical nanosensors for trace metals detection in water matrices. Some perspectives on the development of smart electrochemical nanosensors are also introduced. Full article

Abstract:

In this research, a chemically amplified sensor based on paste electrode modified with Pt/SWCNTs nanocomposite and 1-butyl-2,3-dimethylimidazolium hexafluorophosphate (Pt/SWCNTs-BDHF-PE) was fabricated and used as analytical device for sensing of glutathione as an important biological compound. The Pt/SWCNTs-BDHF-PE showed an excellent catalytic activity on oxidation signal of glutathione in biological condition and improved its oxidation current 3.2 times. Detection limit of 10 nM was detected for sensing of glutathione using Pt/SWCNTs-BDHF-PE as new sensor. In the final step, the Pt/SWCNTs-BDHF-PE successfully used for sensing of glutathione in pharmaceutical and biological samples with acceptable recovery data and standard addition method.
