摘要:The effect of chemical functional groups and condition of supersaturated solutions are two important factors to induce the nucleation of hydroxyapatite onto the substrates. Two kinds of self-assembled monolayers were prepared to create functionalized surfaces by grafting thioalcohol molecular containing hydroxyl and methyl as terminal groups respectively onto single silicon chips. Atomic force microscopy and X-ray photoelectron spectroscopy were used to analyze the topography of the surfaces and estimate the surface density. The results provided the evidences that our experiments were made with almost the same density of chemical functional groups. The surfaces were incubated in the supersaturated solutions (37 degrees C, pH = 7.4) whose Ca2+ and PO43- concentrations were 1.5 times higher than in simulated body fluid. With the condition mentioned above, this study demonstrates that the growth process and morphology of HAp crystals present great differences. (C) 2012 Published by Elsevier B.V.
