Area of Science:

  • Materials Science
  • Nanotechnology
  • Robotics

Background:

  • Microrobots offer potential for targeted delivery and manipulation in biological environments.
  • Developing biocompatible and precisely controllable microrobots remains a significant challenge.

Purpose of the Study:

  • To fabricate and characterize magnetic polymer composite (MPC) microrobots.
  • To investigate the controlled actuation of these microrobots using external magnetic fields.
  • To assess the biocompatibility of the developed MPC material.

Main Methods:

  • Fabrication of magnetic microstructures using two-photon polymerization (TPP).
  • Composition of MPC using magnetite (Fe3O4) nanoparticles and SU-8 photocurable resin.
  • Characterization of material properties and cytotoxicity via live/dead staining tests.
  • Demonstration of controlled motion using uniform rotating magnetic fields.

Main Results:

  • MPC microrobots were successfully fabricated with varying nanoparticle concentrations.
  • MPC samples up to 10 vol.% showed negligible cytotoxicity after 24h incubation.
  • Helical microdevices made with 2 vol.% MPC exhibited controlled corkscrew motion in water.

Conclusions:

  • The developed MPC is a promising material for fabricating biocompatible microrobots.
  • TPP enables precise fabrication of magnetic microstructures for robotic applications.
  • Controlled actuation of microrobots using magnetic fields is feasible for micro-scale operations.
