WebJan 8, 2024 · Another possible method is based on dialysis against a solution containing a polymer to apply an osmotic pressure on the dispersion that forces water to move out of the nanoparticle dispersion. This method that is easy to perform avoids formation of aggregates (Vauthier et al. 2008 ). WebThe term nanocarriers comprises nanoparticles, nanospheres, nanocapsules, nanoemulsion, and nano-sized vesicular carriers, that is, liposomes and niosomes. Nanospheres are matrix particles in which drugs have been dispersed in uniform pattern, whereas in nanocapsules, drug is surrounded by a different polymeric membrane.
