rtoz (2530056) writes A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells. A new study from MIT materials scientists reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-vesicle fusion, a crucial process that allows signal transmission between neurons. MIT engineers created simulations of how a gold nanoparticle coated with special molecules can penetrate a membrane. Paper (abstract; full text paywalled).
