Hydroxyapatite Nanoparticle Coating on Polymer for Constructing Effective Biointeractive Interfaces

Figure 7

Silicone surface modification technique through the deposition of zinc- (Zn-) substituted HAp by EFD to achieve for providing bioactive properties to the films. Photographs of the PDMS substrates (a) before and (b) after the EPD and (c) after ultrasonication (US), indicating the maintenance of a flexible state in folding back. (d) AFM topographic images of 0.5-Zn : HAp nanocrystals electrophoretically prepared at coating voltages of 100 V in ethanol and micrographs of the biocompatible properties based on fibroblast ingrowth on the Zn-substituted HAp with the different initial Zn concentrations of (e) 0.0, (f) 2.5, (g) 5.0, and (h) 10 mol% at the culture time of 72 h.
