Researchers at the National University of Singapore (NUS) have developed a high-throughput method to identify gold nanoparticles capable of delivering therapies directly to mitochondria (the energy centers inside cancer cells). By tagging nanoparticles with unique DNA "barcodes," the team was able t o track and compare dozens of designs simultaneously in living tumor models, rapidly identifying those most effective at reaching this critical subcellular target. ...read more read less
