Gold nanoparticles show promise for early detection of heart attacks

15 enero 2015

A novel colloidal gold test strip is demonstrating great potential for early detection of certain heart attacks. Researchers are developing the strip to test for cardiac troponin I (cTn-I); its level is several thousand times higher in patients experiencing myochardial infarctions. The new strip uses microplasma-generated gold nanoparticles. Compared to AuNPs produced by traditional chemical methods, the surfaces of thesenanoparticles attract more antibodies, which results in significantly higher detection sensitivity.
