If so give some reference text so that it would be easier for me to workout.
@Mohammadreza Kamali I AM WORKING WITH POLYMER BASED NANOPARTICLES, SUCH AS CHITOSAN AND PLGA ETC.
Preparation of nanoparticles using vacuum drying is not possible but u can use vacuum drying to remove moisture from ur sample
As stated above, vacuum drying may be used in order to isolate nanoparticles from volatile solvents. Naturally, residual salts or large surfactants will remain. As a warning, sometimes there occurs agglomeration of the nanoparticles during the drying process which is very difficult to reverse even with sonication and other techniques. Often, however, the material may be redispersed successfully.
dear hassan,
we generally use vacuum drying for nanoparticles to remove the moisture, so that they can be stable for long period of time. we won't use this technique for nanoparticles preparation.
hope it is helpful
regards
