On page 3256, Andrew G. Gillies and co-workers describe a gecko synthetic adhesive surface fabricated with magneto-elastomer microridges, which can be controlled remotely with an external magnetic field. By changing the microridge configuration, adhesion can be switched on and off to selectively capture and release particles.
