Scientists from the University of Virginia, the University of Wisconsin-Madison, The Ohio State University, Northwestern University, the University of Tokyo, and the Sakakibara Heart Institute in Tokyo have developed a nanotechnology-based drug delivery system to save patients from repeated surgeries. The approach would allow surgeons to apply a paste of nanoparticles containing hydrogel on transplanted veins to prevent the formation of harmful blockages inside the veins. Not only did this innovation, dubbed "Pericelle," work at three months – when the applied drug supply ran out – but it continued to work at six months and was still working at nine months. The scientists can't fully explain the unexpectedly durable benefits, but they are excited about what it suggests for the potential of their technique.
