Description
Angel Viteri and nine co-authors shared a study in twenty twenty-six. They stimulated heart cells without wires, through a magnetic gel. Electrodes can pace and train cardiac tissue. But they are invasive and imprecise. The team's hydrogel embeds magnetoelectric nanoparticles. Each one has a cobalt ferrite core in a bismuth ferrite shell. They sit in a soft gelatin network that mimics heart tissue.
An external magnetic field makes the particles act. They give off local electric cues, with no wires attached. Microscopy and tomography showed porous, well-mixed gels. The particles stiffened crosslinking by a small amount. They trimmed swelling too. The gels stayed in the soft range that heart tissue prefers. The platform aims at cardiac patches. Clinicians could switch them on from outside the body. They could tune the dose by field, not by surgery.
