Additive manufacturing has revolutionized implantology by enabling the fabrication of customized, highly porous implants. Surface modifications using electrochemical methods can significantly enhance bioactivity and biocompatibility biomaterials, including 3D-printed This study investigates novel coatings on 3D titanium (Ti) samples. Mesh Ti samples were designed subjected to plasma electrolytic oxidation (PEO) form a calcium phosphate coating. Subsequently, layer polydopamine (PDA) was applied. The properties morphology analyzed. Scanning electron microscopy (SEM) energy-dispersive X-ray spectroscopy (EDS) revealed well-developed containing phosphates (including hydroxyapatite), dioxide, polymerized dopamine, suggesting promising bioactive potential. Composite layers incorporating PDA exhibited superior protective compared base PEO coatings.

Magnesium alloys are often used in bone repair surgeries due to their biodegradability and excellent elastic modulus, making them a promising alternative traditional nondegradable implants like titanium alloys. However, rapid degradation rate limits use as the body. To enhance corrosion resistance bioactivity of magnesium alloys, we applied an ultrasonic spray coating on microarc oxidized (MAO) AZ31 alloy, using mixture silk fibroin (SF) nanohydroxyapatite (nHAp). This SF/nHAp composite embeds directly into micropores MAO-treated surface without additional physical or chemical treatment, forming stable interlocked structure. The effects different parameters adhesion interface characteristics were investigated, leading development corrosion-resistant highly biocompatible coating. Further biological evaluations conducted through subcutaneous implantation, assessing vivo samples surrounding tissue response from multiple perspectives. A novel concept tissue-reactive coatings was proposed, suggesting that materials, early stages postimplantation, enable fibrous tissues closely adhere surface, thereby slowing material degradation. As result, bioactive MAO-SF/nHAp significantly enhances reduces hydrogen evolution, promotes regeneration tissues, minimizes postimplant inflammation. approach offers new strategy improve biocompatibility vivo, overall evaluation biodegradable should focus more in-body corrosion.
