The present invention relates to a method for assembling particles having a long axis, a short axis and an average aspect ratio of 10-10,000. The method includes agitating a combination of a first solution, a second solution and the particles in any order to form a mixture wherein one of the first solution and the second solution is in the form of droplets dispersed in the other of the first solution and the second solution and the long axis of the particles is longer than a diameter of the droplets in the mixture, and continuing the agitation until the particles assemble into aggregates of particles with at least 30% of the particles aligned in parallel along the long axis. Aggregate or aggregate composites form by the method are also described.
