Special Issue Information

Dear Colleagues,

Carbons with high electrical conductivity and large surface area have been used for energy and electrochemical sensing applications. The most popular two-dimensional material in the family of carbons is graphene, which has impressive characteristics, including high electrical conductivity and mechanical strength, and large surface area. Using both top-down and bottom-up methods, graphene has been prepared in the form of monolayer, bilayer, and multilayered sheets, in addition to the creation of structural and dimensional analogues, including holey graphene, graphene nanoribbons, and graphene quantum dots for the construction of sensing platforms. In the context of developing electrochemical nanosensors, the transducer (working electrode) surface is modified with graphene-related materials through the introduction of functionalities and structural defects. The graphene surface is also modified with noble metals and transition metals, their oxides, sulfides and phosphide counterparts, and encapsulated with polymers to create core–shell structures for the enhancement of conductivity, surface area, and active binding sites. For biosensor development, enzymes, antibodies, DNA and other bioreceptors are conjugated to the graphene surface through covalent and non-covalent interactions for disease diagnosis. The size, stacking, and orientation of graphene sheets have a strong influence on their conductivity and overall sensing performance. Therefore, the assembly of graphene sheets in aqueous solutions is controlled to create multilayered films and free-standing foams, for enhancing the porosity, and sensitivity, as well as electron and analyte transport. Gaining considerable interest is the area of micro- and nano-array electrodes made of 3D graphene, created using 3D printing and laser scribing.

The aim of this Special Issue is to cover the material graphene and its structural analogues, highlighting their intriguing roles in nanosensor development. Papers addressing the key challenges in the preparation and characterization of graphene-related materials for nanosensor development are welcome.

This Special Issue is open to all researchers who develop graphene-based nanosensors for the high-throughput screening and quantitation of analytes of broad technological interest. We welcome contributions in the form of papers and review articles related, but not limited to, the following topics:

  • Graphene-related nanosensors (optical, electrochemical, and biological methods of detection);
  • Advancements in graphene nanosensors with applications in clinical and on-field settings;
  • Miniaturization and production of compact and wearable graphene-based nanosensors;
  • New methods for the synthesis and processing of graphene-related materials;
  • Understanding the physical, chemical, and biological properties of graphene;
  • Tailoring structural, optical, and electrochemical properties of graphene-related materials;
  • Biocompatibility and toxicity assessments;
  • Quantitation of single and multiple analytes.

Graphene is widely used as the basic materials of nano optical devices and sensors on account of its special structures and excellent photoelectric properties. Graphene is considered as an ideal material for photodetectors because of its ultra-wide absorption spectrum from the ultraviolet to the terahertz band, ultrahigh carrier mobility and ultrafast photoreaction speed. In this study, a photothermal nano-device was made using graphene that was transferred to an electrode using an all-dry viscoelastic stamping method. The nano-device has the advantages of simplicity, high efficiency and instant measurement. This nano-device was used to measure the light absorption of graphene, and the calculated light absorption rate of graphene is basically consistent with previous research results. Experiments on irradiation at different wavelengths and thermal heating at different temperatures show that the nano-device has an excellent response to near-infrared and mid-infrared light. The conclusions provide an experimental basis for the research, design and fabrication of nano-devices, and this device can provide an effective method for detecting light and temperature in areas such as electronic components and solar cells.
