Researchers at the University of North Carolina said the nanoparticles may enable a more targeted and effective delivery of anticancer drugs than current treatments and have the potential to reduce side effects associated with chemotherapy. The nanoparticles are designed at the molecular level to attack specific kinds of cancer without harming healthy cells.

"I think this will transform the way one detects and treats cancer," study leader Joseph DeSimone, UNC chemistry professor and director of the school's Institute for Advanced Materials, Nanoscience and Technology, said in a prepared statement.

The new custom nanoparticles are the most uniform, shape-specific drug delivery particles developed to date, the researchers said. In cell studies, they were able to attach to specific cell targets, release chemotherapy drugs inside cells, and also hold MRI contrast agents.

The findings were to be presented Sunday at a meeting of the American Chemical Society in Atlanta.

Animal studies with the custom nanoparticles began recently, and human studies are expected to follow, the researchers said. – (HealthDayNews)
