Paragraph starter

The application of magnetic hyperthermia, as explored by Gavilán et al. (2025), presents a novel method for material actuation. By embedding magnetic nanoparticles within a material matrix, localized heating can be induced via an external alternating magnetic field, leading to controlled physical transformations such as polymer de-swelling or enhanced catalytic activity. This principle offers a pathway for designing responsive systems where material properties can be precisely altered on demand.
