Special Issue Information

Dear Colleagues,

The discovery of an atomically thin layer of graphene has unlocked exploration on a wide range of two-dimensional (2D) layered materials. Recently, various 2D materials, such as graphene, boron nitride (BN), transition metal dichalcogenides (TMDCs), and Mxenes, etc. have been significantly explored for different purposes. These emerging 2D materials display a wide range of unique physical, chemical, and electronic properties suited for comprehensive applications ranging from catalysis, sensors to high-performance devices. Besides, these materials are reported to be of excellent biocompatibility and hence of much importance for biosensing applications.

The scope of this Special Issue is to provide a recent finding on various 2D-layered materials, including TMD heterostructures, functionalization/doping of 2D materials such as graphene, h-BN, and other layered 2D structures. Authors are welcome to submit research articles, communications, reviews, and perspectives focused on synthesis techniques, advanced characterizations, novel properties, including computation/DFT studies. More importantly, findings related to bandgap engineering, electronic properties, and applications related to biosensor fabrications are of much interest. 

Submissions are welcome, particularly those including, but not limited to, the following areas: 

1) Synthesis of 2D materials and characterizations

2) 2D heterostructures including stacking of layers

3) Electronic properties, bandgap engineering, etc.

4) Studies on thermal, electrical, and mechanical properties

4) DFT studies on 2D materials

5) Studies including device fabrications, and sensors

6) Applications studies related to catalysis, and biosensors

Over the last decade, we have been witnessing the rise of two-dimensional (2D) materials. Several 2D materials with outstanding properties have been theoretically predicted and experimentally synthesized. 2D materials are good candidates for sensing and detecting various biomolecules because of their extraordinary properties, such as a high surface-to-volume ratio. Silicene and germanene are the monolayer honeycomb structures of silicon and germanium, respectively. Quantum simulations have been very effective in understanding the interaction mechanism of 2D materials and biomolecules and may play an important role in the development of effective and reliable biosensors. This article focuses on understanding the interaction of DNA/RNA nucleobases with silicene and germanane monolayers and obtaining the possibility of using silicene and germanane monolayers as a biosensor for DNA/RNA nucleobases’ sequencing using the first principle of Density Functional Theory (DFT) calculations with van der Waals (vdW) correction and nonequilibrium Green’s function method. Guanine (G), Cytosine (C), Adenine (A), Thymine (T), and Uracil (U) were examined as the analytes. The strength of adsorption between the DNA/RNA nucleobases and silicene and germanane is G > C > A > T > U. Moreover, our recent work on the investigation of Au- and Li-decorated silicene and germanane for detection of DNA/RNA nucleobases is presented. Our results show that it is possible to get remarkable changes in transmittance due to the adsorption of nucleobases, especially for G, A, and C. These results indicate that silicene and germanene are both good candidates for the applications in fast sequencing devices for DNA/RNA nucleobases. Additionally, our present results have the potential to give insight into experimental studies and can be valuable for advancements in biosensing and nanobiotechnology. Full article
