Named AuFeAuNDs, the new nanomaterial features a disk-shaped structure with gold on the outer layers and iron in the middle. This design provides greater stability compared to traditional spherical nanomaterials.

When a magnetic field is applied near a tumor, the iron component acts like a “magnet,” guiding the nanodisk directly to the tumor site. This targeted delivery significantly enhances treatment effectiveness while minimizing collateral damage.

Another key innovation is the nanodisk’s photoacoustic (PA) imaging capability, which allows real-time tracking of the material inside the body. Using a laser beam to heat the nanodisk, the process generates vibrations that are captured via ultrasound and converted into images.
