Abstract
Spherical nano-sized particles of poly(D,L-lactide-co-glycolide) (PLGA) with molar composition of D,L-lactide and glycolide 75:25 mol.% synthesized with non-toxic catalyst bismuth subsalicylate were produced by a nanoprecipitation method. The effect of the formulation parameters (i.e. concentrations of PLGA in the organic phase and poly(vinyl alcohol) (PVA) in the aqueous phase) on the average hydrodynamic diameter, polydispersity index and electrokinetic potential of the PLGA particles was revealed. A formation mechanism of the PLGA particles based on the “nucleation and aggregation” model was proposed and supported by experimental data. Steric and electrokinetic stabilization factors of the PLGA particles were analyzed and discussed. • The nucleation and aggregation mechanism of PLGA particles formation was proposed. • The effect of formulation parameters on properties of PLGA particles was studied. • Stable surfactant-free PLGA particles were produced by a nanoprecipitation. • Structure of PVA - free and PVA-stabilized PLGA particles was studied by SAXS. • Biocompatibility of particles based on BiSS-synthesized PLGA was established.
