Sterically stabilized diblock copolymer nanoparticles with an intensity-average diameter of 25 nm are prepared in the form of a concentrated aqueous dispersion using polymerization-induced self-assembly (PISA). The addition of n-dodecane followed by high-shear homogenization produces n-dodecane-in-water Pickering macroemulsions of 22-46 μm diameter. If the nanoparticles are present in sufficien...

The rational design of drug delivery systems has led to enhanced targeting, increased efficiency, and a reduction side effects in chemotherapies vaccines. As most biological reactions took place at the interface, particle-stabilized emulsion (Pickering emulsion), may offer major implications for advanced loading, delivery, controlled release. In fact, it is aggregating particles that determined...

Oil-in-water emulsions have been stabilized by functionalized cellulose nanofibrils bearing either a negative (oxidized nanofibrils, OCNF) or positive (cationic CCNF) surface charge. The size of the droplets was measured laser diffraction, while structure shell Pickering emulsion probed using small-angle neutron scattering (SANS), confocal scanning microscopy (CLSM), electron (SEM), and rheolog...

[To my family for their love and support] iv ACKNOWLEDGEMENTS There are many people I would like to thank for their support throughout my Ph.D. study at Georgia Tech. I would like first express my tons of gratitude to my advisor Dr. Behrens for his invaluable support that I will remember for ever. I will remember his great guidance whenever I encounter a problem in my thesis work; I will rememb...
