Ordered volume submicron surface structures "nanoflowers" - are obtained while growing metal nanowires in porous membranes by means of pulsed current electroplating. These structures occur if the electroplating is continued after the nanowires appear on the membrane surface. Various ordered Ag, Pb, PdNi and PbIn volume structures of complex shape resembling living plant organisms are produced. Some of the structures are formed by spherical and ellipsoidal nanoclusters. Membrane geometry and pulsed current electroplating parameters are the main factors, which determine the shape formation process of these ordered structures at the surface of porous membranes. Choosing the membrane geometry, electrolyte composition and pulsed current electroplating parameters one can deliberately fabricate volume ordered complex shape nano- and submicron structures of various metals and alloys. Such objects can be of interest for fundamental research as well as for applications in catalysis, electronics, optics, medicine, etc.
