Shape-shifting nanoparticles flip from sphere to net in response to tumor signal
San Diego CA (SPX) May 29, 2013
Scientists at the University of California, San Diego, have designed tiny spherical particles to float easily through the bloodstream after injection, then assemble into a durable scaffold within diseased tissue. An enzyme produced by a specific type of tumor can trigger the transformation of the spheres into netlike structures that accumulate at the site of a cancer, the team reports in the journal Advanced Materials this week. Targeting treatments specifically to cancerous or other diseased cell ... read more
