The main figure shows a three‐dimensional, branched fractal pattern of gold nanoparticles created via dielectrophoresis. Initially, a silver‐gallium nanoneedle is mounted on the end of a pulled glass capillary and coated with a thin layer of gold. A conductive coverslip (not pictured) is used to complete the point‐and‐plate system. A...
A high aspect ratio 3D electrokinetic nanoprobe is used to trap polystyrene particles (200 nm), gold nanoshells (120 nm), and gold nanoparticles (mean diameter 35 nm) at low voltages (<1 Vrms). The nanoprobe is fabricated using room temperature self‐assembly methods, without the need for nanoresolution lithography. The nanoprobe (150–500 nm in diameter, 2–150 μm in length) is mounted on the end...
