Abstract

Graft block copolymers of poly(ɛ-caprolactone) containing various amounts of dextran [dextranpoly(ɛ-caprolactone) copolymers] have been prepared and characterized. The methods of obtaining nanoparticles based on the dextran-poly(ɛ-caprolactone) graft block copolymers have been elaborated and optimized. It has been demonstrated that the electrokinetic potential of nanoparticles may be varied relative to the composition of the polymer, the structure of nanoparticles, and the ionic strength of solution. Under physiological conditions, the nanoparticles behave as stable colloids. On the basis of the experimental evidence, conclusions concerning the structure of the nanoparticles have been made.
