Early detection of heart attack
Why is it in news?
- A low-cost, ultra-sensitive device that is capable of detecting the cardiac biomarker troponin T protein has been fabricated by a research team from the Indian Institute of Technology (IIT) Hyderabad.
More in news
- Troponin T: It is a cardiac protein that is released into the bloodstream after a heart attack.
- Comparison with existing devices: Unlike the commercially available test that can detect the protein at nanogram per ml concentration, this device can detect the protein at an extremely low concentration of femto gram per ml.
- Early diagnosis of a heart attack: This could help pave the way for early diagnosis of a heart attack, increasing a patient’s survival rate. It even has the potential to be able to predict the onset of a heart attack.
- Cost-effective fabrication: Unlike electrodes that are available, it costs very little to fabricate this bioelectrode. This is because a commercially available substrate was used. Further, very little antibody was needed to coat the electrode.
