Cancer Drug Delivery Research At Case Western Reserve University Speeds Time From Two days To Two Hours
Posted Jul 27 2008 11:09am
Researchers at Case Western Reserve University have developed a technique that has the potential to deliver cancer-fighting drugs to diseased areas within hours, as opposed to the two days it currently takes for existing delivery systems.
Using laboratory mice, drug delivery time from injection to the cancer cells was reduced from two days to mere hours. Using this as a model for potential human use, cancer patients may someday soon receive the benefits of cancer-fighting drugs within hours of injection.
Findings are discussed in a paper, co-authored by Clemens Burda, associate professor of chemistry and director of the Center for Chemical Dynamics and Nanomaterials Research at Case Western Reserve University and graduate student Yu Cheng, appearing in the current edition of the Journal of the American Chemical Society .
The system uses gold nanoparticle vectors to deliver photodynamic therapy (PDT) drugs through the bloodstream to cancerous sites.
