Aptasensor-based point-of-care detection of cardiac troponin biomarkers for diagnosis of acute myocardial infarction

Acute myocardial infarction (AMI) represents a critical health challenge characterized by a significant reduction in blood flow to the heart, leading to high rates of mortality and morbidity. Cardiac troponins, specifically cardiac troponin I and cardiac troponin T, are essential proteins involved in cardiac muscle contraction and serve as vital biomarkers for the diagnosis of AMI. Aptasensors utilize synthetic aptamers or peptides with high affinity for specific biomarkers and offer a promising approach for integration into portable, user-friendly point-of-care (POC) applications. This review explores recent advances in POC aptasensor-based platforms for the rapid detection of cardiac troponin biomarkers. Furthermore, this review addresses current challenges and potential future directions in the development of aptasensor. Also, it highlights their potential to improve timely and accurate diagnosis in clinical and emergency settings.
