Mini rice-sized robots repair the heart
Researchers at Johns Hopkins University have developed tiny magnetic robots, about the size of a rice grain, capable of delivering antibiotics directly to infected tissues inside the heart. The technology relies on two robots working together: one anchors itself at the infection site, while the other carries the medication and attaches magnetically to it, gradually releasing the antibiotics. Tests conducted on models resembling the human heart and pig tissues, including blood flow conditions, have been successful. Future experiments aim to ensure safety and effectiveness. The goal of this development is to reduce the treatment time for heart infections from weeks to a day or less, with the potential for the technology to be later used to deliver cancer medications.
