When synthetic nanoparticles enter a biological cell they usually damage the cell membrane by creating tiny transient holes in it. Now, researchers in the US report on a new way of overcoming this problem - by coating the particles with "stripes" of different molecules. The breakthrough technique, which allows the nanoparticles to pass directly though the cell membrane barrier and reach the cell cytosol, could come in handy for drug delivery and for investigating macromolecular interactions in biology.
