Patterns of grooves etched into the surface of a silicon chip can guide, trap and filter migrating cells, biomaterials scientists from Japan and Korea have discovered. The results open the way to engineering surfaces to study the movement of particular cell types during development and cancer, or to confine cells in tissue culture and protect against interference by cellular invaders. As the technique is biologically non-invasive, it should be ready for use in biomedical applications without years of safety testing.
