Dr. Min-young Lee and Dr. Sung-gyu Park of the Advanced Bio and Healthcare Materials Research Division at KIMS have developed a technology that can detect cancer mutant genes in blood with the world's highest sensitivity of 0.000000001% based on plasmonic nanomaterials for optical signal amplification. The team tested blood samples from lung cancer patients (stages 1-4) and healthy individuals for EGFR mutations and achieved a diagnostic accuracy of 96%.
