A new class of microwires and a method for their assembly from suspensions of metallic nanoparticles in water under the influence of dielectrophoretic forces. The wires are formed in the gaps between planar electrodes in an alternating current (AC), allowing manipulation of the particles without the interference of electro-osmotic and electro-chemical effects resent in direct current (DC) systems. The structures created cover a new size domain of microwires of micrometer diameter and millimeter to centimeter length, closing the gap between tradition metallic wires and the more recently synthesized nanowires and carbon tubes. The wires have good Ohmic conductance and their thickness, conductivity, and fractal dimension can be controlled by varying the frequency and voltage of the applied field. The formation of such self-assembled structures can be used in miniaturization of electrical circuits for application in sensors, memory elements, and wet electronic circuits, such as electrically readable bioarrays and biological-electronic interfaces.

A vortex reactor includes a reactor body having first and second ends, with one or more inlet ports coupled to the first end. The reactor is configured to form one or more vortices in a fluid passed into the reactor. The inlet port(s) may be positioned to advance a reactor fluid into the reactor body at an angle tangential to an inner surface of the reactor body, forming a vortex that advances toward the second end along the inner surface of the reactor body.
