McGill University researchers report in a new study that nanoscale "cages" made from strands of DNA can encapsulate small-molecule drugs and release them in response to a specific stimulus. The research, published online Sept. 1 in iNature Chemistry/i, marks a step toward the use of biological nanostructures to deliver drugs to diseased cells in patients. The findings could also open up new possibilities for designing DNA-based nanomaterials. "This ...
