Three Dimensional Stainless Steel Bone Scaffolds: Using the Electrochemical Technique to Coat Hydroxyapatite on Stainless Steel Braids

Abstract:

Ceramics and metallic material are commonly used in biomedical filed. Ceramic material, such as hydroxyapatite (HAP), is bioresorbable and has osteoconduction and osteoinduction. Metallic material, such as stainless steel (SS), possesses good mechanical properties and chemical stability. Thus, the study aim was combination of the two together can form the bone scaffold applied in bone tissue engineering, providing desirable support, cell growth, and cell attachment for bone tissue. This study method is braid the SS filaments into a three-dimensional structure of braid. By electrochemical technique, HAP is then coated on the braid, forming the three-dimensional HAP/SS bone scaffold. Simulated body fluid, the electrolyte solution, is heated into various temperatures to simulate the environment, and the current supplied in the electrochemical technique remains constant. A scanning electron microscope (SEM) observes the surface of the scaffold, and energy dispersive spectrometer (EDS) further evaluates the HAP attachment in terms of calcium-phosphorus (Ca/P) ratio, determining the optimal Ca/P ratio that is similar to that of human bone tissues to accelerate recovery of bone tissues. The result shows three-dimensional HAP/SS bone scaffolds are covered with HAP particles.
