Abstract

The adsorption behavior of hydroxyapatite nanocrystals onto a model substrate was investigated using a Quartz Crystal Microbalance (QCM) technique. Self-assembled monolayers (SAMs) of alkanethiol having NH ₂, CH ₃, COO ^- and terminal groups were formed on a QCM substrate via sulfur attachment. The frequency shift of QCM increased in the following order: NH ₂ < CH ₃ < COO ^-. The adhesion properties were tested by Atomic Force Microscopy (AFM) where peeling forces were evaluated. These studies on adsorption behavior and bond strength between HAp and substrates will be applied to the control of the surface morphology of hydroxyapatite/polymer composite.
