Cardiac troponin detection in one drop of saliva or urine for 10-minute assessment of acute myocardial infarction

The printed immunosensing photonic crystal biochip (PCB) is the first non-invasive tech for 10-min CTnT detection (0.25 pg/mL, 10 μL), outperforming ELISA with ≥99.8% consistency for AMI rapid diagnosis and health management.
