Researchers from Boston Children’s Hospital and Massachusetts Institute of Technology have developed a targeted drug-delivery system that’s based on a combination of ultraviolet (UV) light and short, single strands of DNA called aptamers.  The study is published in the Proceedings of the National Academy of Sciences (PNAS). Aptamers hold appeal as drug delivery tools, or as drugs themselves, because they’re small size, penetrate tissues rapidly and … Continue reading Researchers use DNA paired with light to deliver drugs on target.
