چکیده

DOI: 10.1002/admi.201400187 The propensity of Au ions to self-assemble and undergo rapid reduction into colloids and NPs, however, poses distinct barriers for utilizing conventional gold chemistry for creating structurally-defi ned, organized wire structures and thin fi lms. Patterned Au structures have been produced through chemical derivation of gold colloids surfaces [ 14 ] and/or the substrate employed for surface deposition, [ 15–17 ] or through the aid of physical templates. [ 18–22 ]

Individual Template-Stripped Conductive Gold Pyramids for Tip-Enhanced Dielectrophoresis

Gradient fields of optical, magnetic, or electrical origin are widely used for the manipulation of micro- and nanoscale objects. Among various device geometries to generate gradient forces, sharp metallic tips are one of the most effective. Surface roughness and asperities present on traditionally produced tips reduce trapping efficiencies and limit plasmonic applications. Template-stripped, no...

Dramatic shape modulation of surfactant/diacetylene microstructures at the air-water interface.

Langmuir monolayers constitute a powerful platform for self-assembly and organization of amhiphilic molecules. Controlling the structural features of condensed domains formed within Langmuir monolayers, however, is a challenging task. The formation of remarkably diverse condensed microstructures is demonstrated in binary monolayers comprising of a surfactant (octadecylmelamine) and a diacetylen...

Control and modeling of the dielectrophoretic assembly of on-chip nanoparticle wires.

Suspensions of metallic nanoparticles in water were assembled via the action of an alternating electric field (dielectrophoresis) into wires of micrometer thickness. Two modes of microwire assembly, one through the bulk of the suspension and one as half-cylinders on the glass surface between the electrodes, were identified. The operating conditions responsible for the two assembly modes were re...
