A multi-functional nanoplatform for efficacy tumor theranostic applications

Area of Science:

• Biomedical Engineering
• Materials Science
• Nanotechnology

Background:

• Multifunctional nanomaterials are increasingly vital in cancer research.
• Molybdenum disulfide (MoS₂) shows promise for photothermal therapy, imaging, and drug delivery.

Purpose of the Study:

• To synthesize and evaluate a water-soluble MoS₂-PEG nanosystem for combined drug delivery, photothermal therapy (PTT), and X-ray imaging in cancer treatment.

Main Methods:

• Synthesized water-soluble MoS₂-PEG nanosystem.
• Loaded Doxorubicin (DOX) onto MoS₂-PEG, achieving ~69% drug loading efficiency.
• Evaluated *in vitro* and *in vivo* efficacy, including cell uptake, apoptosis, and anti-tumor effects.

Main Results:

• MoS₂-PEG/DOX demonstrated efficient cell membrane crossing and endosomal escape upon NIR irradiation.
• Achieved enhanced apoptosis in MCF-7 cells and superior anti-tumor efficacy compared to free DOX.
• Showcased excellent tumor targeting, synergistic chemo-photothermal therapy, and X-ray contrast properties.

Conclusions:

• MoS₂-PEG/DOX is a promising multifunctional platform for simultaneous cancer diagnosis and photothermal-chemotherapy.
• The nanosystem offers potential for improved cancer treatment with reduced toxicity.
• Highlights the significant potential of MoS₂-based nanomaterials in advanced cancer therapy.
