Discussion

Aptamer-based assay improves detection of cardiac troponin I in resource-limited settings, indicating high accuracy and stability.

Detection limit was 11.70 ng·mL−1 for cardiac troponin I, and recovery rates ranged from 95.11% to 103.17%.
Assessment using a dual-aptamer sandwich system on a lateral flow assay demonstrated excellent analytical accuracy.
Stability was confirmed with test strips remaining effective after four months at room temperature.
This method supports timely detection of acute myocardial infarction in point-of-care settings.

Zhang et al. (2025) studied this question.
