Scientists have been developing drones to clear the arteries by latching on to hard plaques like fat, cholesterol and calcium.

The microscopic stealth drone are made up of plastic-like material and about 1,000 times smaller than the tip of human hair. The nanoparticles will keep the arteries fine and release a drug derived from natural protein thus repairing the inflammation damage in the body.

Experiments on lab mice, has shown perfect results after 5 week treatment. Researchers have therefore concluded that more tests were needed before the drones are tested on humans. For the human trials a fine tune of particles, which would enable optimised drug delivery is being planned. The mice were fine enough without any heart damage or sickness weeks after the experiment.

If this innovation becomes real, many people can avoid the risk of heart attacks or CVAs.
