Laser method detects cancer's molecular fingerprints in blood

Researchers have developed a new method for cancer detection using pulsed infrared light to analyze blood plasma. This technique identifies molecular patterns, potentially indicating the presence of certain cancers. The method, called electric-field molecular fingerprinting, contrasts with traditional methods that require invasive procedures. The study analyzed blood plasma from over 2,000 participants, using machine learning to link molecular patterns to lung cancer. The model showed up to 81% accuracy in detecting lung cancer signatures. The study demonstrates a potential for broader application in disease detection, offering a less invasive alternative. While successful for lung cancer, accuracy was lower for other cancer types. The researchers plan further study to expand the method to other cancers and health conditions. They hope to improve the technology for more reliable diagnostics and broader clinical applications.
