Modes development of PLGA scaffolds modification by magnetron co-sputtering of Cu and Ti targets

Abstract

Bioresorbable scaffolds from poly(lactide-co-glycolide) (PLGA) were formed by electrospinning. Then, plasma modification of PLGA scaffolds was carried out by magnetron co-sputtering of copper and titanium targets in Ar. The surface morphology, elemental composition and mechanical properties of the obtained samples were investigated. The modes of plasma modification were selected that could preserve the macrostructure, morphology and mechanical properties of PLGA scaffolds.
