Nanoparticles play at being red blood cells - physicsworld.com
"Nanoparticles disguised as red blood cells could be used to deliver anti-cancer drugs directly to a tumour. So say researchers at the University of California at San Diego, whose new technique is unique in its approach to harnessing nanoparticles.
Drug delivery systems that mimic naturally occurring biological molecules seem to be the most efficient when it comes to delivering drugs to tumours. Such systems – usually based on nanoparticles – can also circulate in the body for extended periods of time without being rejected by the body's immune system."
