Abstract
It is important to the scaffold with honeycomb structure for tissue engineering because of shortage of donors. In recently, scaffold made of segmented polyurethane (SPU) has been investigated as a new scaffold's material. However, surface condition of the scaffold must be modified by any process because the SPU is not enough for biocompatibility. To solve this problem, Diamond-Like Carbon (DLC) films, with much attractive properties such as biocompatibility, chemical stability and anti-corrosion, are fabricated on the scaffold with honeycomb structure. The samples were evaluated by scanning electron microscope, Raman spectroscopy, X-ray photoelectron spectroscopy, and contact angle measured. The biocompatibility of the samples has been estimated using the mouth fibroblasts (NIH-3T3) cells in the D-MEM solution while 4 days. These analyses show that the DLC coating on scaffold with honeycomb structure is expected for surface finishing treatment with biocompatibility.
