Using Nanotechnology to Improve Treatment for Stroke Victims

Enhanced stroke treatment uses magnetically controlled nanomotors to transport a clot-busting drug to blockages

UGA Researchers including Physics Professor Yiping Zhao have developed a new technique to enhance stroke treatment using magnetically controlled nanomotors to transport a clot-busting drug to blockages in blood vessles. Results of this new technique are published in the Journal ACS Nano, and is featured in UGA's Research News. The clot-busting drug, recombinant tissue plasminogen activator, or t-PA is usually delivered to blood clots intraveneously.  In the UGA Research story, Dr. Zhao explains that “Our technology uses magnetic nanorods that, when injected into the bloodstream and activated with rotating magnets, act like stirring bars to drive t-PA to the site of the clot. Our preliminary results show that the breakdown of clots can be enhanced up to twofold compared to treatment with t-PA alone.” You can read more about this potentially life-saving research in the UGA Research Blog.
