The particles that carry cholesterol through the bloodstream is known popularly as “bad” or “good” are bad if they deposit cholesterol in blood vessel walls and can clog, and good if you carry cholesterol to the liver for excretion.

Now, scientists have created tiny particles in the laboratory that mimic the good cholesterol and collected before it can accumulate in deposits and form dangerous plaques. The surfaces of these new particles are coated with fat and protein, which can be linked seamlessly with the sticky and transport cholesterol through the bloodstream.

The particles could one day become important for the treatment of cardiovascular disease, said Dr. Andre Nel, chief of the division of nanomedicine and director of the environmental implications of nanotechnology at the University of California, Los Angeles.

The researchers have endowed the artificial particles with the same properties with natural particles circulating in the blood”, called high density lipoprotein or HDL, she said. These vehicles can clean artificial sites that otherwise, plaques may rupture, leading to strokes and heart attacks.
