Chemotherapy timing is key to success, research shows

Nanoparticles that stagger delivery of two drugs knock out aggressive tumors, new research shows. In studies with mice, the research team showed that this one-two punch, which relies on a nanoparticle that carries two drugs and releases them at different times, dramatically shrinks lung and breast tumors. "With a nanoparticle delivery platform that allows us to control the relative rates of release and the relative amounts of loading, we can put [two] systems together in a smart way that allows them to be as effective as possible," one researcher explains.
