A schematic diagram of the SWCNT electrical immunosensor with two pairs of concentration and detection electrodes.

An electrical immunosensor has been developed to detect acute myocardial infarction within a minute. The system works by measuring the level of cardiac troponin I (cTnI), a protein that is excreted by the heart muscle into the blood following a heart attack. Prof. Jang states, “This new immunosensor is constructed in a different way than any other sensor.” He adds, “Owing to the new design of this immunosensor, this device is able to rapidly diagnose the level of heart attacks at the point of care.”

It is a a rapid, label-free, and highly sensitive single-walled carbon nanotube (SWCNT) electrical immunosensor, featuring two pairs of electrodes...

Bilirubin – Wikipedia

Mildly elevated levels of a bile pigment bilirubin may provide natural protection from heart attacks and help to stave off cardiovascular disease. The study shows that when hearts are infused with bilirubin following a heart attack, the pigment reduces damage and improves heart function during recovery.

“This is a very important finding as very few drugs are able to be administered following a heart attack to improve heart function,” says Dr Bulmer. “Generally, if it is a small heart attack people can survive. However there is a 20% mortality rate from heart attack, with approximately 50,000 heart attack sufferers each year in Australia.

“Generally, bilirubin was just associated with people having jaundice; however we have now shown that mildly elevated bilirubin is a...
