By injecting a solution of nanoparticles around the heart, a temporary heart stimulator self-assembles, which can correct heart arrhythmia in emergency situations with the help of an external power source.
Lund UniversityAug 27 2024 After treatment, the electrode spontaneously disappears from the body. The study was conducted on animals.
We have developed an injectable heart stimulator for emergency situations, which consists of a syringe loaded with a solution of nanoparticles." Nanoparticles are extremely small particles. Because the particles are so small, they can be injected with a needle thinner than a human hair. When the solution comes into contact with tissue, a structure forms around the heart consisting of a long chain of molecules—a so-called polymer—that conducts electricity. The injected electrode integrates with the body's cells and facilitates ECG measurements, can regulate heartbeats, and correct arrhythmia.
Owing to the intimate contact between the polymer and the heart tissue, the stimulator can operate with low power inputs which can come from handheld devices. Most people carry their mobile phones everywhere, and with the help of a cable attached to the skin at the injection site near the heart, charges from the phone can be transferred to the conductive electrode in the body.
