Tiny Robots Race Against the Current

The Challenge with Current Microrobots

• Movement: Struggle in fast-flowing blood
• Control: Poor response to magnetic fields

The Breakthrough

Scientists have developed a new method to create microrobots with strong magnetic properties:

1. 3D Printing: Molds are created using a 3D printer.
2. Magnetic Slurry: Molds are filled with a special magnetic mixture.
3. Result: Robots that move like tiny screws through water.

The Advantages

• Speed: Up to 3 millimeters per second
• Efficiency: 22.6 times their body length every second
• Direction: Can move against the flow of blood

The Future

• Potential: Deliver medicine directly to needed areas
• Challenges:
• Ensuring safety
• Precise control
