The first direct near-field optical images from a superlens have been obtained by researchers in Germany and the US. Superlenses are made of negative refractive index metamaterials and this breakthrough could lead to their use in enhancing near-field microscopy for imaging biological samples and materials used in electronics (Science 313 1595).
