Nanometer-sized drones that deliver a special type of healing molecule to fat deposits in arteries could become a new way to prevent heart attacks caused by atherosclerosis, if an animal model developed by scientists at Columbia and Harvard universities is a guide.  In the study, biodegradable nanoparticles, loaded with a molecule that promotes healing, were injected into mice with advanced atherosclerosis. The nanoparticles were designed … Continue reading Nanobot ‘drones’ successfully target atherosclerosis in animal model.
