Abstract

Methods of forming a plurality multiphasic nano-components (MPNs) having at least two phases, with high selectivity for at least one of shape, size, or phase orientation in the nano-component are provided. The methods provide high yields of substantially similar nano-components by controlling one or more of: polymer concentration, liquid stream composition, liquid stream conductivity, flow rate, humidity, temperature, pressure, electrode design and/or configuration during an electrified jetting process. Such methods of making MPNs form shapes including disks, rods, spheres, rectangles, polygons, toroids, cones, pyramids, cylinders, fibers, and combinations thereof. Such MPNs can be used in various applications, including for medical diagnostics or with pharmaceutical, personal care, oral care, and/or nutritional compositions.
