Special Issue Information

Dear Colleagues,

In the last decade, the extent of effort dedicated in the field of nanomaterials has grown exponentially. This interest is due to their excellent electrical, optical, thermal, and catalytic properties and strong mechanical strength, ensuring that in recent years various nanomaterials (e.g., carbon nanotubes, gold nanoparticles, silicon nanowires, and quantum dots) have been extensively explored as innovative electrode materials for environmental and electrochemical sensing applications. The use of nanoparticles as transducers, parts of electrochemical sensors for antioxidant detection, adsorbents, analyte carriers, and markers in electrochemical immunosensors continues to arouse considerable interest due to their ability to detect and measure toxic metal ions, toxic gases, pesticides, and hazardous industrial chemicals with high performance in terms of sensitivity, selectivity, and simplicity. At the same time, there has been a growing need for more sensitive, reliable, and affordable sensors and detectors for applications from industrial monitoring to homeland security. This Special Issue on “Electrochemical Properties and Applications of Nanomaterials” will attempt to cover the most recent advances in nanostructures, concerning not only their synthesis and characterization, but especially their functional and smart properties to be applied in advanced sensing and detecting applications. The articles presented in this Special Issue will cover various topics, ranging from different techniques for their synthesis and morphological modification to the preparation of electrochemical sensors and their use in several areas of interest, such as environmental, industrial, and health-medical monitoring and sensing applications. Therefore, this Special Issue welcomes contributions from all researchers working on nanomaterials and their application in electrochemical sensing.

The Special Issue will cover, but will not be limited to, the following topics:

  • Nanomaterial-enabled sensors;
  • Multifunctional materials;
  • Enzymatic biosensors;
  • Metallic nanoparticles as sensors;
  • Electrochemical and optical properties of nanomaterials;
  • Sensors for environmental monitoring.

It is our pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are welcome.

Accepted papers are published in the joint Special Issue in Nanomaterials or Nanomanufacturing (https://0-www-mdpi-com.brum.beds.ac.uk/journal/nanomanufacturing/special_issues/electro_nano).

Conducting nanofibers of polyaniline (PANI) doped with camphor-10-sulfonic acid (HCSA) and blended with different polymers, such as polymethyl methacrylate (PMMA) and polyvinyl acetate (PVAc), have been fabricated using the electrospinning technique. Scanning electron microscopy (SEM) and thermal gravimetric analysis (TGA) were utilized to characterize the morphology and the thermal stability of PANI-blended fibers. An extensive study was performed to understand the copolymer influence on both the structural and surface properties of the realized conductive thin films. Samples main electrical characteristics, as conductivity, specific capacitance and electrochemical performances were tested. The better mats were obtained with the use of PVAc copolymer, which showed a conductivity value two orders of magnitude higher than the PMMA system. Aiming at further improving the electrochemical features of these blended mats, hybrid fibers based on PANI/PVAc/graphene oxide and PANI/PVAc/iron oxide were also produced and characterized. The obtained mats were potentially addressed to numerous practical fields, including sensors, health applications, smart devices and multifunctional textile materials. Full article

The continuous decrease in the availability of fossil resources, along with an evident energy crisis, and the growing environmental impact due to their use, has pushed scientific research towards the development of innovative strategies and green routes for the use of renewable resources, not only in the field of energy production but also for the production of novel advanced materials and platform molecules for the modern chemical industry. A new class of promising carbon nanomaterials, especially graphene quantum dots (GQDs), due to their exceptional chemical-physical features, have been studied in many applications, such as biosensors, solar cells, electrochemical devices, optical sensors, and rechargeable batteries. Therefore, this review focuses on recent results in GQDs synthesis by green, easy, and low-cost synthetic processes from eco-friendly raw materials and biomass-waste. Significant advances in recent years on promising recent applications in the field of electrochemical sensors, have also been discussed. Finally, challenges and future perspectives with possible research directions in the topic are briefly summarized. Full article
