Development of methods of producing nano-dispersion for industrial application

Research Abstract

Have you ever noticed the oil droplets that appear in the water when you wash your dishes after dinner? You actually produce a very important system called emulsions. When the droplet sizes are in nanometres (10-9m) and with long-term physical stability, they are invisible to human's eyes but they are very useful in applications such as cosmetics, drug delivery, personal care and nanoparticle synthesis. Nano-emulsions can act as nano-reactors to synthesize nanoparticles. The chemical reactions between reactants occur in the droplets to produce particles that will grow inside the core of the emulsions. Thus, the particle sizes can be controlled if the emulsion sizes are controllable. However, not much work has been undertaken on producing nanoparticles through nano-emulsions. Nanoparticles are important in many diverse applications due to their unique magnetic, optical and surface reactivity properties. The aim of this research is to develop and investigate the production of nanoparticles via nano-emulsions. The formation of nano-emulsions will be investigated in order to develop an optimum method for producing nanoparticles.
