Doctors can now get a high-resolution 'fingerprint' of a heart attack in a single test, rather than checking one biomarker at a time.

The Takeaway
Currently, if you think you're having a heart attack, doctors check for a few specific proteins in your blood, which can take time and isn't always 100% clear. This new technology uses 'nanoswitches' to detect 60 different genetic targets all at once. It’s the difference between looking at a grainy photo of a suspect and having their full DNA profile and fingerprints. This massive increase in detail allows for a much faster and more accurate diagnosis, especially in 'borderline' cases. For regular people, this means getting the right treatment minutes earlier, which can be the difference between a full recovery and permanent heart damage.
From the abstract
Acute myocardial infarction (AMI) remains a leading cause of global mortality, where timely diagnosis is critically hampered by the limited sensitivity and specificity of conventional biomarkers like troponin. While circulating microRNAs (miRNAs) offer immense potential as potential biomarkers, their clinical translation has been stalled by the absence of accurate, sensitive, specific, and multiplexed detection platforms. Here, we report a highly multiplexed nanopore sensing platform that integr
