Inspired by the simplicity of alcohol and mercury thermometers, the researchers created a similarly straightforward way to detect troponin.
It involves a few easy steps, a glass vial, specialized nanoparticles, a drop of ink and a skinny tube.
Troponin’s concentration rises when blood is cut off from the heart, and the muscle is damaged.
Today, detecting troponin requires bulky, expensive instruments and is often not practical for point-of-care use or in low-income areas.
Yet three-quarters of the deaths related to cardiovascular disease occur in low-and middle-income countries. Early diagnosis could help curb these numbers, the researchers said.
