Abstract
Polymeric biomaterials offer excellent bulk properties for biological applications; however, the surface properties they possess do not lend themselves to high performance in regard to biomimetics. Hence, it is necessary to vary the surface properties of the material to enhance the wettability and bioactivity. In the present contribution, the surface characteristics and properties of nylon 6,6 modified by \(\hbox{CO}_{2}\) laser processing has been presented in detail. From analyzing the laser-induced patterned surfaces it was found that the surface energy and polar component had decreased by up to \(7\,\hbox{mJm}^{-2}\) and the surface roughness had considerably increased. From the results it was not possible to develop a discernable correlation between the cell response and surface characteristics such as roughness and surface energy. However, laser patterned surfaces in this instance gave rise to enhanced biomimetic properties for nylon 6,6 in terms of osteoblast cell response.
