New Developments of Molybdenum Sheets in Medical and Bioengineering Fields

In the fields of medical and bioengineering, molybdenum and its compounds, especially molybdenum disulfide (MoS2), have shown numerous new developments. Here is a detailed overview of these advancements:

  1. Biomedical Applications of Molybdenum Disulfide (MoS2):
    • Due to their unique physical and chemical properties, MoS2 has been extensively studied in the biomedical field. It can be utilized for drug delivery, cancer therapy, bioimaging, and various other applications.
    • For instance, studies have shown that MoS2-based biomaterials demonstrate potential in cancer therapy, killing cancer cells through different mechanisms such as photothermal therapy and photodynamic therapy.
    • Furthermore, MoS2 can be combined with other materials, such as graphene oxide, to form nanocomposites that exhibit excellent performance in drug delivery and tumor targeting.
  2. Synthesis and Properties of Molybdenum Nanosheets:
    • The synthesis methods of molybdenum nanosheets are diverse, including sputtering and sulfurization steps. These nanosheets possess remarkable physical and chemical properties such as high specific surface area and good chemical stability.
    • By controlling the synthesis conditions (e.g., temperature, pressure), molybdenum nanosheets with different thicknesses and properties can be produced. For instance, continuous, uniform, and fully covered MoS2 films can be prepared at 750°C and 1 KPa.
  3. Application of Molybdenum in Bioimaging:
    • Molybdenum and its compounds can also be used in bioimaging. By combining them with specific biomolecules, imaging of specific tissues or cells within the biological body can be achieved, providing crucial information for disease diagnosis and treatment.
  4. Application of Molybdenum Nanocomposites in Tumor Targeting and Drug Delivery:
    • Molybdenum nanocomposites, such as MoS2/graphene oxide nanocomposites, have demonstrated significant potential in tumor targeting and drug delivery. These nanocomposites can selectively target tumor tissues and effectively deliver drugs to the target sites, thereby enhancing therapeutic effects and reducing side effects.
  5. Biocompatibility and Safety:
    • Biocompatibility and safety are crucial considerations when applying new materials in medical and bioengineering fields. Studies have shown that MoS2 and its nanocomposites exhibit good biocompatibility and no significant toxicity in vitro and in vivo, providing important guarantees for their applications in the biomedical field.
