    A new blood test developed at Johns Hopkins University can diagnose heart attacks in 5–7 minutes using SERS technology.

  • 2

    The test detects key cardiac biomarkers like CK-MB, myoglobin, and cardiac troponin-I, which indicate heart attacks.

  • 3

    The metasurface-enhanced chip amplifies signals in SERS, improving detection sensitivity for biomarkers at ultra-low concentrations.

  • 4

    The technology allows simultaneous detection of multiple biomarkers by tracking frequency shifts in the SERS signal.

  • 5

    Future applications may include use by first responders and adaptation into a hand-held device for home diagnostics.
