New screening method shows how nanoparticles interact with human cells

Scientists at the Brookhaven National Laboratory have developed a screening method to examine how newly made nanoparticles interact with human cells following exposure for various times and doses. Using this new method, the investigators have been able to visualize how human cells interact with some specific types of carbon nanoparticles.
