Abstract
AbstractThe successful application of artificial implants requires osseointegration in the implanted structures. To stimulate bone growth, synthetic hydroxyapatite obtained by the coprecipitation process was coated onto porous stainless steel substrates in order to enhance the biocompatibility and, consequently, mineralization. The substrate of choice was porous 316L stainless steel for its high resistance, mechanical strength and low density due to its foam structure. The aim of the present study was to investigate the biological response of the fabricated implants cultured with MC3T3‐E1 mouse osteoblast‐like cells by analyzing the variation in the elemental concentration, mainly calcium, along with the cellular differentiation and mineralization. By employing synchrotron radiation x‐ray fluorescence spectroscopy (SRXRF), intracellular elemental distribution and concentration could be determined, revealing a clear increase in the total calcium content. This preliminary data suggests that synthetic hydroxyapatite on porous stainless steel substrates might be successfully used for biocompatible medical implants.
