Area of Science:

  • Biomedical Engineering
  • Materials Science
  • Nanotechnology

Background:

  • 2D layered molybdenum disulfide (MoS2) shows promise for biomedical uses due to biocompatibility and tunable photothermal properties.
  • Limitations like poor aqueous stability and low tissue accumulation hinder MoS2's clinical translation.
  • Developing advanced MoS2-based platforms is crucial for overcoming these challenges.

Purpose of the Study:

  • To develop multifunctional MoS2-based magnetic helical microrobots (MoSBOTs) using Spirulina platensis as a biotemplate.
  • To combine remote magnetic navigation with MoS2's photothermal activity for therapeutic applications.
  • To enable targeted cancer cell ablation and biorecognition in oncotherapy.

Main Methods:

  • Fabrication of MoS2-based microrobots using Spirulina platensis as a biotemplate.
  • Integration of magnetic properties for remote navigation.
  • Utilizing near-infrared (NIR) irradiation for photothermal activity.
  • Demonstrating targeted photothermal ablation of cancer cells and biorecognition capabilities.

Main Results:

  • Successful creation of MoSBOTs with combined magnetic navigation and MoS2 photothermal properties.
  • Effective targeted photothermal ablation of cancer cells using MoSBOTs under NIR irradiation.
  • Demonstrated on-the-fly biorecognition capabilities for diagnostic applications.

Conclusions:

  • MoSBOTs offer a promising solution to overcome limitations of traditional MoS2 in biomedical applications.
  • The multifunctional microrobots show potential for minimally invasive oncotherapy, combining ablation and diagnostics.
  • This approach holds significant promise for advancing cancer treatment and diagnostic strategies.
