Formation of arrays of metallic nanodots by a new, versatile, bottom-up approach is described. Spherical reverse micelles are loaded with a metal salt and then deposited onto a smooth substrate, exploiting their self-assembly into an ordered array. Exposure to an oxygen or hydrogen plasma is demonstrated to reduce the salt to the corresponding metal and simultaneously remove the polymer matrix without destroying the order. The Figure shows a gold nanoparticle array formed in this way.
