“…For example, DNA-functionalized layered TMDs have also attracted great interest for fabricating biosensors to detect miRNA-21 expression in cancer cell-based tumor microenvironments [76]. Mohamed Atef et al [77] investigated the MoS 2 field effect transistor with a nanopore served for DNA base detection using the first-principle modeling. Both MoS 2 sheet and MoS 2 FET sensors exhibit distinct electronic characteristics for the different DNA nucleobases (Thymine, Adenine, Cytosine, and Guanine).…”

The unique nano–bio interfacial phenomena play a crucial role in the biosafety and bioapplications of nanomaterials. As a representative two-dimensional (2D) nanomaterial, molybdenum disulfide (MoS2) has shown great potential in biological applications due to its low toxicity and fascinating physicochemical properties. This review aims to highlight the nano–bio interface of MoS2 nanomaterials with the major biomolecules and the implications of their biosafety and novel bioapplications. First, the nano–bio interactions of MoS2 with amino acids, peptides, proteins, lipid membranes, and nucleic acids, as well as the associated applications in protein detection, DNA sequencing, antimicrobial activities, and wound-healing are introduced. Furthermore, to facilitate broader biomedical applications, we extensively evaluated the toxicity of MoS2 and discussed the strategies for functionalization through interactions among MoS2 and the variety of macromolecules to enhance the biocompatibility. Overall, understanding the nano–bio interface interaction of two-dimensional nanomaterials is significant for understanding their biocompatibility and biosafety, and further provide guidance for better biological applications in the future.

“…Carbon nanotubes, transition metal dichalcogenides (TMDs), phosphorene are all good potential flexible materials in terms of outstanding electronic, optical and high mechanical flexibility. Especially MoS 2 are of great interest due to their wide application in optoelectronic devices, thin-film field effect transistor, and chemical sensors [11][12][13]. MoS 2 is an ideal candidate for high-performance flexible and transparent electronics because of its better long-term stability compared to organic semiconductors [14,15].…”

Monolayer molybdenum disulfide (MoS2) is considered a promising candidate for high-performance flexible nanoelectronics in the future. The robustness of conductivity against bending is critical for the stability of flexible electronic devices. We proposed an all-MoS2 nanoribbon-based junction consisting of a 2H semiconducting phase MoS2 nanoribbon sandwiched between two 1 T metallic phase MoS2 electrodes. The junction exhibits better conducting behavior due to the contribution of the nanoribbon’s edge states and is insensitive to the bending angle of the semiconducting region when the bending angle is close up to 30°. These results suggest that this system is very promising for flexible nanoelectronics.
