An additively manufactured medical implant, comprising a metallic body having at least one porous surface configured to promote bony on-growth or in-growth of tissue, the porous surface being replicated from a high resolution scan of bone, and a biological surface coating configured to create a barrier to particulate debris, the biological surface coating being produced from a titanium porous plasma spray surface coating or a biomimetic coating.

The invention relates to a preparation method of a traditional Chinese medicine monomer sequence slow-released calcium-phosphorus support material for osteogenesis and angiogenesis. The method comprises the steps of 1, preparing calcium-phosphorus crystal supports; 2, slowly releasing an osteogenesis coating; 3, slowly releasing an angiogenesis coating; 4, repeating functional particles for 2-5 cycles and conducting crystallization and freeze-drying for use, wherein the operation is carried out in a sterile environment, and the calcium-phosphorus supports in the desired size and shape are prepared according to different clinical needs. The method has the advantages that a low-temperature micro-nano-deposition technique is used for sequentially and circularly carrying traditional Chinese medicine monomer components including salvianolic acid B and notoginsenoside R1 to construct the composite biomimetic calcium-phosphorus support material capable of promoting osteogenesis and angiogenesis at the same time. According to the low-temperature micro-nano-deposition technology, a biomimetic coating is prepared, calcium-phosphorus micro-nano crystals are formed in a buffer system, and thecrystals can be condensed into the supports with certain strength at normal temperature.

The invention discloses an antifouling biomimetic coating with low adhesion of oil and fat and a preparation method of the antifouling biomimetic coating. Dolphin elastic skin is adopted as a basic research model of the coating, and the coating is obtained through crosslinking of polymer materials with a high elastic modulus and a low surface energy. Through control on the cross-linking density ofthe coating, change of low surface energy content and other parameter control, the adhesion resistance of the coating to various oil and low-surface-tension liquids is achieved. The coating has excellent oil adhesion resistance in both static and dynamic environments. The coating can be applied to multiple substrate surfaces, and can be applied to surfaces of various metals, ceramics, glass, various polymer materials and other materials, the adhesion between the coating and a substrate is high, and good transparency, flexibility, corrosion protection and other performance are achieved; and the coating is mainly applied to ventilation device blades, fume hood fan blade parts, smoke exhaust ventilator fan blade parts and other fan blade parts, and has a good application prospect and economic significance in reduction of surface oil stain and dust pollution, reduction of energy consumption, improvement of the work efficiency and reduction of energy consumption.

The invention discloses a preparation method of a silver / fibroin / hydroxyapatite biomimetic coating-modified artificial ligament. The method concretely comprises the following steps: 1, carrying out surface modification on an artificial ligament material, carrying out plasma processing, taking out and exposing the material to air, feeding the material into a grafting agent solution, cleaning the material with pure water and drying the material in vacuum, so as to obtain the surface-modified artificial ligament material; and 2, adding a soluble silver salt to a fibroin solution, adding a calcium source, stirring the solution to form a mixed solution, feeding the surface-modified artificial ligament material to the mixed solution, fully stirring the solution evenly, irradiating under sunlight or artificial visible light, sucking up by a filter paper, putting into a Na2HPO4 solution, standing still, then taking out and sucking up; and repeating the cycle. Compared with the prior art, the preparation method disclosed by the invention has the advantages of the biocompatibility and the osteoconduction property of the artificial ligament material can be improved, and the artificial ligament has antibacterial and anti-inflammatory properties, and can meet the requirements of clinical medicine on the aspects of biological activity and mechanical property.
