Polysaccharides as Stabilizers for Polymeric Microcarriers Fabrication.

ABSTRACT: Biodegradable polymeric microparticles are widely used in drug delivery systems with prolonged-release profiles and/or cell microcarriers. Their fabrication via the oil/water emulsion solvent evaporation technique has normally required emulsifiers in the aqueous phase. The present work aims to evaluate the effectiveness of various polysaccharides, such as chitosan, hyaluronic acid, cellulose, arabinogalactan, guar and their derivatives, as an alternative to synthetic surfactants for polylactide microparticle stabilization during their fabrication. Targeted modification of the biopolymer's chemical structure was also tested as a tool to enhance polysaccharides' emulsifying ability. The transformation of biomacromolecules into a form of nanoparticle via bottom-up or top-down methods and thei
