Excess of cholesterol can cause build up of fat that can clog blood vessels and it all can cause heart attacks and strokes. Particles that carry cholesterol throughout the blood vessels (carrier), popularly known as “good” (HDL – High-density lipoprotein) or “bad” (LDL – Low-density lipoprotein). Called “bad” cholesterol when excess is dragged causing fat accumulation or blockage in the artery walls (atherosclerosis), whereas “good” cholesterol is given when they are able to bring cholesterol back to the liver for disposal.

Now, scientists have created the small particles in laboratory-like good particle carriers, so that cholesterol can be transported before they could settle and cause plaques. Particle surface is coated in fat and protein so they could tie themselves with cholesterol for subsequent transport to the blood vessels.

These particles in the future will be important in the treatment of cardiovascular disease management. These particles have the same shape as the natural HDL particles circulating in the blood. This artificial substance carrier capable of cleaning the blood vessels and there are plaques can rupture and cause a stroke or heart attack. HDL particles are made is not only useful for cardiovascular therapy but also diagnosis. To facilitate monitoring, the experts also put metal objects and gold in the center of the particle. So these particles will be visible through imaging technology. Studies in the field of nanotechnology particles that produce good cholesterol (HDL), if there are no proven side effects, we can make it as a drug to prevent the plaque in arteries. This will be a revolution in the field of cardiology.
