Gelatin Immobilization on Titanium Surface by Gamma Irradiation

Radiation induced graft polymerization of 2-hydroxyethyl acrylate (HEMA) on titanium surface and couple gelatin have been studied in the paper. The composition and properties of surface modified titanium were investigated by several surface sensitive techniques: X-ray photoelectron spectrum (XPS) and scanning electron microscopy (SEM). Results of the technological measurements show that surface chemistry is affected throughout the surface modification process, finally leading to a complete and homogeneous vinyl compound overlayer on top of the titanium samples. And the modified porous titanium exhibits an interesting mineralization in simulated body fluid (SBF) and an adsorptive property in bovine serum albumin (BSA).
