Examples of nanostructures synthesized by Dr. Velev: a) thick structured porous gold1; b) thin gold film on substrate2,3; c) anisotropic "supraparticles",4 d) doughnut-like aggregates4; e) microscopic biosensor patch5; f) gold microwire via dielectrophoretic assembly6.

The scale bars in a) and b) are 1 mm, in c) and d) 500 mm.
