Nanoemulsions, like nanoemulsion, metoprolol/lecithin nanoemulsion and nanoemulsion, are subject to ongoing research as shown in figure 1 and 2. A lot of the reported synthesis procedures include homogenization, emulsification or stirring during the preparation. Amongst the most actively researched properties of nanoemulsions are stability, viscosity and drug release. Very often nanoemulsions are characterized by either dynamic light scattering, transmission electron microscopy or UV. High impact articles within this field report applications in medicine/veterinary, drug delivery or cosmetics/sunscreens/lotions.
