Spray of tiny particles of gold can potentially treat heart disease, research suggests acsnano
Cutting-edge research led by University of Ottawa Faculty of Medicine Associate Professors Dr. Emilio Alarcon and Dr. Erik Suuronen suggests a spray-on technology using customized nanoparticles of one of the world's most
offers tremendous therapeutic potential and could eventually help save many lives. Cardiovascular diseases are the leading cause of death globally, claiming roughly 18 million lives each year., a peer-reviewed journal that highlighted the new research on its supplementary cover, Dr. Alarcon and his team of fellow investigators suggest that this approach might one day be used in conjunction with coronary artery bypass surgeries. That's the most common type of heart surgery.
The therapy tested by the researchers—which was sprayed on the hearts of lab mice—used very low concentrations of peptide-modified particles ofcreated in the laboratory. From the nozzle of a miniaturized spraying apparatus, the material can be evenly painted on the surface of a heart within a few seconds.
Gold nanoparticles have been shown to have some unusual properties and are highly chemically reactive. For years, researchers have been employing gold —so tiny they are undetectable by the human eye—in such a wide range of technologies that it's become an area of intense research interest.
