Liquid Biopsy for Brain Tumor Biomarker Developed

Scientists at Washington University in St. Louis say they have developed a technique that allows them to detect brain tumor biomarkers through a simple blood test. Hong Chen, Ph.D., a biomedical engineer, and Eric C. Leuthardt, M.D., a neurosurgeon, led a team whose proof-of-concept method permits biomarkers from a brain tumor to pass through the tough blood–brain barrier into a patient's blood using noninvasive focused ultrasound and some tiny bubbles, potentially eliminating the nee
