- The nanoparticles are designed to latch on to hard plaques in the arteries, made from fat cholesterol and calcium, which cause heart disease. Each of the tiny particles, made from a plastic-like material, is 1,000 times smaller than the tip of a human hair.
- Once they reach their target, the "drones" release a drug derived from a natural protein that repairs inflammation damage in the body. The nanoparticles are made from a biodegradable polymer that dissolves away in the body over time and is used in a number of approved medical products.
- In the tests, atherosclerosis [clogged arteries] in laboratory mice was significantly repaired after five weeks of treatment and plaques were stabilised, making it less likely for fragments to break off and clog blood vessels.
Drones could be used to seek out arteries to prevent heart attacks
