Nanopackaging biodegrades after delivering cancer drug

DNA binding creates potentially nontoxic tumor-targeting structures

TINY DELIVERY  Nano-sized packaging, made from different sized nanoparticles (gray dots) linked by strands of DNA, can deliver cancer drugs directly to tumors and then safely biodegrade in the body. Researchers have found an easy way to alter the size and structure of the packages. The scale bar represents 50 nanometers.
