Abstract

Abstract

The degradable performance and bio-mineralization function of bioglass/poly(lactic acid) tissue engineering scaffolds were systematically studied in the simulated body fluid (SBF) by measuring pH value of SBF, the loss mass rate of the scaffolds and analyzing SEM pictures, XRD and FTIR spectra of scaffolds' surface. It was found that in SBF, the pH value of SBF with bioglass/poly(lactic acid) tissue engineering scaffolds and the mass of bioglass/poly(lactic acid) scaffolds decreases with the prolongation of time. SEM pictures and XRD, FTIR spectra showed that there appears the deposition of carbonate hydroxyl apatite on the surface of the bioglass/poly(lactic acid) tissue engineering scaffolds. The result shows that the bioglass/poly(lactic acid) tissue engineering scaffolds have good bio-mineralization function.
