Science Nation: Nanosponge Decoy Fights Superbug Infections

With support from the National Science Foundation, Liangfang Zhang and his team at UC-San Diego have created a nanosponge to combat drug-resistant infections, such as those caused by Methicillin-resistant Staphylococcus aureus (MRSA). The nanosponge, made from biocompatible, biodegradable polymer nanoparticles, is camouflaged with a red blood cell membrane. It circulates in the bloodstream, absorbing the toxins produced by infection. Once the nanosponges are fully loaded with toxins, they are safely disposed of by the liver. They are designed to work with any type of infection or poison that attacks the cellular membrane. Part of the National Science Foundation Series “Science Nation.”
