In this dissertation, the novel applicability of the electrified jetting process for the control of materials distribution in nanometer scale is demonstrated. Simultaneous jetting of two or three distinct polymer solutions through jetting capillaries in a side-by-side geometry was employed to create biphasic or triphasic nanocolloids. The resulting nanocolloids consist of two or more separate compartments, which generates anisotropy. Various materials such as biomolecules, functionalized polymers, and inorganic nanocrystals were selectively incorporated into the individual phases of the nanocolloids. Selective surface modifications and chemical reactions combined with electrified co-jetting enabled demonstration of the novel concept of directional cell-membrane labeling. Selective incorporation of superparamagnetic nanocrystals in one hemisphere of nanocolloids opened a new route to control the orientation of a nano building block. The potential applications of these anisotropic nanocolloids with unique functionalities include drug delivery, bio-imaging, and novel displays.... diagram 24 Figure 2.1 Biphasic electrified jetting using side-by-side dual capillaries, a: Schematic diagram of the experimental setup used ...
