1. A method of forming a nano-component comprising at least one colorant, the method comprising:
- forming a composite stream by contacting a portion of a first liquid stream with a portion of a second liquid stream, wherein said first and second liquid streams are compositionally distinct from one another and at least one of said first and second liquid streams comprises a colorant; and
exposing at least a portion of the composite stream to an electric force field sufficient to form a solid nano-component comprising a first phase and a second distinct phase, wherein said first phase comprises material from said first liquid stream and said second phase comprises material from said second liquid stream, such that said first phase and said second phase are compositionally distinct from one another.

Abstract
Multiphasic colorant nano-components (MPCs) having at least two phases and at least one colorant are provided. In certain aspects, the at least two phases are optically or visually distinct from one another. The MPCs can be used in various methods in various applications, such as visual, optical, and/or electronic displays, including in paints, inks, coatings, plastics, textiles, electronic display devices, pixels, or electronic paper. The MPCs are formed by methods of electrified jetting of polymers.
