Review—Opportunities for Rapid, Sensitive Detection of Troponin and Cerebral Spinal Fluid Using Semiconductor Sensors
2019
Journal of the Electrochemical Society
Preserved Fulltext
Cardiac troponin I (cTnI) in cardiac muscle tissue is a standard clinical biomarker for AMI, as its concentration rises quickly in the blood during release from myocardial cells following cell death. ...
The challenge is to develop a real-time, accurate, low-cost point-of-care heart attack sensor. ...
