Abstract
A method of forming multi-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.
Claims34
A nano-object having at least one spatial dimension of about 5 nm to about 5000 nm comprising multiple chemically distinct exposed surface regions, wherein at least two of the multiple chemically distinct exposed surface regions independently comprise a polymeric material.
A nano-object having at least one spatial dimension of about 5 nm to about 5000 nm comprising at least two phases each independently comprising a polymeric material wherein the nano-object has at least two distinct exposed surface regions, wherein the nano-object has a morphology selected from the group consisting of spheres, rods, fibers and combinations thereof.
A nano-object having at least one spatial dimension of about 5 nm to about 5000 nm comprising at least two chemically distinct phases that form multiple chemically distinct exposed surfaces to define sides of the nano-object, wherein each of the at least two chemically distinct phases independently comprises a polymeric material.
