Title:
抗菌性組成物、抗菌性組成物を含む骨再生用材料、及びその製造方法
Document Type and Number:
Japanese Patent JP7083975
Kind Code:
B2
Abstract:
To provide a highly safe silver-based antimicrobial composition that exhibits antimicrobial property early in accord with the decomposition and absorption of calcium compound after a bone regeneration material is implanted in the body and that yet has a low risk of developing cytotoxicity.SOLUTION: By mixing a calcium acetate solution and a silver nitrate solution to generate a white precipitate, followed by adding thereto nitric acid to dissolve and prepare a sample solution, followed by subjecting to ultrasonic spray pyrolysis to produce a hollow approximately spherical calcium carbonate particle in which silver nanoparticles are distributed and deposited approximately homogeneously on the surface, and thereby an antimicrobial inorganic filler is obtained.SELECTED DRAWING: Figure 4
