A new method to isolate polyalkylcyanoacrylate nanoparticle preparations.

Abstract:

:A simple method for the separation of polyalkylcyanoacrylate nanoparticles was developed using polyisohexylcyanoacrylate (PIHCA) as a model. Fluorescein isothiocyanate dextran 70 was used to label the nanoparticles. Ultracentrifugation onto a performed sucrose gradient allowed the easy elimination of the dextran and of the free molecules remaining in the upper phase. After such treatment, the physicochemical characteristics of the PIHCA nanoparticles were not modified. This method could be usefully extended to other types of nanoparticles.
