Structure and Properties of different forms of MoS2 Nanostructures

What is Molybdenum disulfide?

MoS2 has a 2D layered structure with each layer of thickness of about 0.65 nm, which are heaped upon each other to form a bulk. Weak van der Waals forces clasp these layers together. MoS2 exists in three different crystal structures, namely, a trigonal phase (1T), a hexagonal phase (2H), and a rhombohedral phase (3R). The letters in the representation correspond to the crystal structures, whereas the digits represent the number of monolayers in the unit cell. The Mo–S coordination is octahedral in the IT phase, while the coordination is trigonal prismatic in the 2H and 3R phases, respectively. Naturally, existing MoS2 crystals (e.g., molybdenite) mostly occur in the 2H phase, which is also the thermodynamically stable phase, while synthetic MoS2 mainly comprises 1T and 3R phases and is metastable. The next section describes different forms of MoS2 nanostructures.

 
Structure and properties of different forms of MoS2 nanostructures

The diverse electronic properties of TMDs result from filling the non-bonding d bands from group 4 to group 10 species. TMDs exhibit metallic properties when the orbitals are partially occupied, whereas when the orbitals are fully occupied, TMDs display semiconducting properties. On the contrary, compared to the influence of metal atoms, chalcogen atoms exhibit a minor impact on the electronic structure; however, it is examined that upon broadening the d bands, the band gap decreases by increasing the atomic number of the chalcogen.

MoS₂ nanostructures can be synthesized in three primary morphologies: nanosheetsnanotubes, and quantum dots, each offering distinct properties. MoS₂ nanosheets are the most widely studied form, consisting of single or few-layer 2D sheets with high surface area and excellent electronic properties. The band gap of MoS₂ increases with decreasing layer number, transitioning from an indirect band gap (~1.2 eV) in bulk to a direct band gap (~1.8 eV) in monolayer form. This tunable band gap makes nanosheets suitable for photodetectors, solar cells, and light-emitting devices. MoS₂ nanotubes are formed by rolling single or multiple layers into cylindrical structures, similar to carbon nanotubes. They exhibit enhanced mechanical strength and chemical stability compared to nanosheets, and their hollow interior provides additional surface area for catalytic applications. MoS₂ quantum dots are zero-dimensional nanoparticles with sizes typically below 10 nm. Due to quantum confinement effects, quantum dots exhibit size-dependent photoluminescence, making them attractive for bioimaging, sensing, and optoelectronic applications. The high surface-to-volume ratio of quantum dots also enhances their catalytic activity and interaction with biological systems. In addition to these three main forms, MoS₂ can also be synthesized as nanowires, nanoflowers, and other hierarchical structures, each offering unique properties for specific applications. The choice of morphology depends on the intended application, with nanosheets favored for electronics, nanotubes for composites, and quantum dots for biomedical applications. The synthesis method, including hydrothermal, solvothermal, chemical vapor deposition, and exfoliation techniques, significantly influences the morphology, crystallinity, and properties of the resulting nanostructures. Recent research has focused on developing scalable, cost-effective synthesis methods to produce high-quality MoS₂ nanostructures for commercial applications. The ability to functionalize the surface of MoS₂ nanostructures with polymers, biomolecules, or other nanomaterials further expands their application potential in biomedicine, sensing, and energy storage.

MoS2-based nanostructures for biomedical applications

It has not highlighted its use in tissue engineering applications. Another review by Yadav et al. describes the application of 2D MoS2-based nanostructures specifically for biosensing, bioimaging, and therapeutics. Moreover, the review of Nguyen et al. mainly focuses on the surface properties of 2D materials, from biosensing to tissue engineering. However, no dedicated review has been published on the application of MoS2 nanostructures in tissue engineering applications. In the current review, we aim to explore the three main structural morphologies of MoS2, i.e., nanosheets, nanotubes, and quantum dots, with their inherent properties. The review also focuses on the interaction of MoS2 nanostructures with biological systems. This review also sheds a spotlight on the utility of MoS2-based scaffolds for various tissue engineering applications. Finally, the review highlights some key shortcomings in using MoS2-based materials for tissue engineering applications that could be addressed to make this potential material a significant performer for next-generation tissue engineering applications.

The application of MoS₂ nanostructures in biomedical fields has gained significant momentum in recent years. In biosensing, MoS₂ nanosheets and quantum dots have demonstrated excellent sensitivity for detecting biomolecules such as glucose, DNA, and proteins, due to their high surface area and unique electronic properties. The fluorescence quenching ability of MoS₂ makes it suitable for developing "turn-on" and "turn-off" sensors with low detection limits. In bioimaging, MoS₂ quantum dots exhibit strong photoluminescence with high photostability, making them ideal for cellular imaging and real-time tracking of biological processes. Their low toxicity and biocompatibility further enhance their suitability for in vivo imaging applications. In therapeutics, MoS₂ nanostructures have been explored as drug delivery carriers due to their large surface area and capacity for loading therapeutic agents. The photothermal properties of MoS₂ enable its use in cancer therapy, where near-infrared light can be converted to heat to destroy tumor cells. MoS₂ nanosheets have also been used in combination with chemotherapy drugs to achieve synergistic therapeutic effects. In tissue engineering, MoS₂-based scaffolds have shown promise for enhancing cell adhesion, proliferation, and differentiation. The layered structure of MoS₂ provides a favorable microenvironment for cell growth, and its mechanical properties can be tailored to match specific tissues. MoS₂ can also be incorporated into polymer composites to create scaffolds with improved mechanical strength and bioactivity. Despite these promising applications, several challenges remain, including the long-term biocompatibility and biodegradability of MoS₂, the controlled release of therapeutic agents, and the potential toxicity of degradation products. Future research should focus on addressing these challenges to enable clinical translation of MoS₂-based biomedical devices. The interaction of MoS₂ nanostructures with biological systems, including cellular uptake, intracellular trafficking, and immune response, requires further investigation to ensure safe and effective use. The development of multifunctional MoS₂-based platforms that combine sensing, imaging, and therapeutic capabilities is an exciting direction for future research.
