It should be pointed out that the external phase dominates the emulsion's conductivity [20, 39, 40].
However the effect of PLGA depends on the effect of internal-external phase volume ratio since the drug that was originally encapsulated would finally be affected by the high external phase volume, thus neutralizing the role of PLGA in drug encapsulation.
The entrapment was also found high when the external aqueous phase was saturated with B12 and further increased when the saturated external phase was reduced to 10 ml.
These values can be explained by the fact that the diffusion occurs mainly through the water which is contained in cryogels and which can also migrate from the continuous external phase.
Another new feature is a "full intensity" external phase contrast system, which is incorporated into the microscope body, rather than in the objective lens.
The treated powder goes into the external phase of a water-in-oil (W/O) emulsion and not to the interphase as emulsions are then more stable.
All microsponges were prepared by a quasi-emulsion solvent diffusion method using an external phase of containing 200 ml distilled water and 40 mg polyvinyl alcohol (PVA) 72 000 (Tansel et al.
