1. A method of forming nano-objects, the method comprising:
- combining two or more liquid streams together such that the two or more liquid streams contact over spatial dimensions sufficient to form a composite liquid stream; and
exposing at least a portion of the composite liquid stream to a force field sufficient to form a nano-sized cone jet thereby solidifying the composite liquid stream into the nano-objects, the nano-objects comprising multiple phases and multiple chemically distinct exposed surface regions.

Abstract
A method of forming mufti-phasic nano-objects involves the jetting of two or more different liquids in side-by-side capillaries thereby generating a composite liquid stream. The composite then exposed to a force field which causes the composite liquid stream to at least partially solidify into a nano-object. The method forms a nano-object having a number of morphologies such as rods, spheres, and fibers.

17. A method of forming nano-objects, the method comprising:
-
combining two or more liquid streams together at a nozzle such that the two or more liquid streams contact over spatial dimensions sufficient to form a composite liquid stream having a nano-sized cone-jet; and exposing at least a portion of the composite liquid stream to an electric field sufficient to solidify the composite liquid stream into the nano-objects, the nano-objects comprising multiple phases and multiple chemically distinct exposed surface regions, wherein the nano-objects have a spatial dimension between about 20 nm and about 5,000 nm. - View Dependent Claims (19)

30. A method of forming nano-objects comprising:
-
combining two or more liquid streams together at a nozzle such that the two or more liquid streams contact over spatial dimensions sufficient to form a composite liquid stream having a nano-sized cone-jet, wherein one or more of the liquid streams comprise a component selected from the group consisting of liquid solutions, curable polymer precursors, polymer solutions, polymer melts, and combinations thereof and one or more of the liquid streams further comprises an additive selected from the group consisting of inorganic nanocrystals, quantum dots, biomolecules, colorants, crosslinkers, pharmaceutical compounds, molecular probes, molecules that enable drug delivery, and combinations thereof; and exposing at least a portion of the composite liquid stream to an electric field sufficient to solidify the composite liquid stream into the nano-objects, the nano-objects comprising multiple phases and multiple chemically distinct exposed surface regions.
