‘Sticky’ Particles Promise More Precise Drug Delivery for Brain Cancer
A Yale research team has found that by tinkering with the surface properties of drug-loaded nanoparticles, they can potentially direct these particles to specific cells in the brain. By making nanoparticles bioadhesive, or “sticky,” the researchers have answered a long-standing question: Once you get the particles to the brain, how do you get them to interact with the cancer cells there? “Until now, research has focused on whether you can load the nanoparticles with drugs and whether we can get them into the brain at all, without thinking too much about what cells they go to,” said senior author W. Mark Saltzman, the Goizueta Foundation Professor of Chemical and Biomedical Engineering, professor of cellular and molecular physiology and member of the Yale Cancer Center. “This is the first exploration of the particles’ affinity for different cells.”
