Computational imaging-based vertical flow assay for high-sensitivity point-of-care troponin testing

Key Points

• The assay achieved a detection limit of 0.2 pg/mL, indicating high sensitivity for cardiac troponin I.
• Performance was validated against clinical standards, demonstrating clinical-grade reliability in results.
• A large dynamic range was established, allowing for versatile testing in varied patient scenarios.
• The method is cost-effective, potentially improving access to cardiac diagnostics.
