There is only one treatment which is currently approved for the treatment of acute stroke, t-PA, or recombinant tissue plasminogen activator. However, researchers at the University of Georgia have recently reported that the use of t-PA, combined with a newly-developed magnetic nanoparticle can improve the efficacy of this stroke treatment. Patients receiving the treatment would receive a combined injection of the nanomotors along with the t-PA dose. A magnet would stimulate the nanomotors, causing them to spin and thus, further breaking down blood clots which have already been thinned by the t-PA.
Though the technique has only been tested in mice, researchers found that this method was twice as effective as the use of t-PA alone. Ultimately, the research team from the University of Georgia believes that this technique will allow doctors to use less medication for an equally effective treatment.
