Heart Attack: Diagnosis within a minute
Heart attack is one of the most common reasons that cause people’s death. Today, cases of heart attacks are not only seen in men but women as well. People in their old age are more likely to suffer an attack, however, due to changing lifestyles, young also fall prey to them. Also, in most cases death occurs due to non-early detection of heart attacks. 
To tackle such a problem, researchers have developed an electrical immuno-sensor to detect heart attacks and provide results in just one minute. 
The study undertaken by Ulsan National Institute of Science and Technology (UNIST) in South Korea shows that measuring the level of cardiac troponin I (cTnI), a protein that is excreted by the heart muscle into the blood following a heart attack.
So, by using a single drop of blood, the immuno-sensor detects cTnI present in blood and shows the results in just one minute.  
As the presence of protein in blood is not too much, to conduct the study, dielectrophore tic (DEP) forces were applied to attract protein and to reduce detection time, DEP mediated biomarker concentration was used that reduced the detection time from 60 minutes to just one minute. 
The findings were published in the journal Biosensors & Bioelectronics.
