Nanoparticle system captures heart-disease biomarker from blood for in-depth analysis

Researchers at the University of Wisconsin–Madison have developed a method combining sticky nanoparticles with high-precision protein measurement to capture and analyze a common marker of heart disease to reveal details that were previously inaccessible.

The new method, a system known as nanoproteomics, effectively captures and measures various forms of the protein cardiac troponin I, or cTnI, a biomarker of heart damage currently used to help diagnose heart attacks and other heart diseases. An effective test of cTnI variations could one day provide doctors with a better ability to diagnose heart disease, the leading cause of death in the U.S.
