摘要: The methods provided use external fields such as light and electricity as a means of directing the crystallization of concentrated colloidal systems. Not only can nucleation be directed, crystal melting can be carefully controlled and light-induced crystal diffraction used as a means of directing light propagation. A number of factors play a significant role on the crystallization rate and location, including the intensity of the light field, the magnitude of the electric field, the colloid concentration, the colloid size, and the colloid composition. In varying these parameters, kinetics in these processes are extremely fast when compared to traditional colloidal crystallization approaches.

摘要: The present invention relates to the use colloidal particles to realize photonic and microfluidic devices. In particular embodiments, colloidal particles are used to realize microfluidic a two-way valve, three-way valve, check valve, three-dimensional valve, peristalsis pump, rotary pump, vane pump, and two-lobe gear pump. In certain embodiments, actuation of an active element in the microfluidic structure is accomplished by electrophoresis, the use of an optical trap or “tweezer”, or the application of an electric field or magnetic field. In other embodiments, the application of an electrical field to colloidal particles that are substantially constrained to two dimensional movement is used to realize wave guides, filters and switches for optical signals.
