Scientists in Korea have created an AI-powered biosensor that can spot cancer from just one drop of blood and do it in only 20 minutes. The device detects DNA methylation, chemical marks tied to tumor growth, by using gold nanoparticles to massively amplify signals. AI then analyzes the light patterns to identify cancer with 99% accuracy, even distinguishing early-stage tumors from advanced ones. Tested on colorectal cancer patients, the sensor proved highly precise while requiring far less blood than traditional tests. Researchers say it could eventually screen for other diseases, like autoimmune disorders or Alzheimer’s, making this a potential game-changer for fast, non-invasive diagnosis at clinics or even at home.
