Nanocapsules, like dPE/Pluronic nanocapsules, fluorine doped tin oxide glass/double-shell g-C3N4 nanocapsules and mesoporous silica nanocapsules, are subject to ongoing research as shown in figure 1 and 2. A lot of the reported synthesis procedures include hydration, extrusion or solvent evaporation during the preparation. Amongst the most actively researched properties of nanocapsules are drug release, stability and colloidal stability. Very often nanocapsules 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 diagnostics.
