PROBLEM TO BE SOLVED: To provide a new substrate with nano particles, which makes it possible to modify (or alter) surface properties relating to biocompatibility as well as antimicrobial properties in a repeatable and controlled manner.SOLUTION: This invention provides a substrate with an electron donating surface, having metal particles on the surface, the metal particles comprising palladium and at least one metal selected from the group consisting of gold, ruthenium, rhodium, osmium, iridium, and platinum, wherein the amount of the metal particles is from about 0.001 to about 8 μg/cm. In the substrate, the electron donating surface includes silver, the metal particles are dispersed on the electron donating surface and do not form a coating layer, and the metal particles comprising palladium and gold are free from silver. 【課題】反復可能および制御された様式で生体適合性および抗微生物特性に関する表面特性を修飾（又は改変）することを可能とするナノ粒子を有する新規な基体の提供。【解決手段】表面に金属粒子を有し、金属粒子はパラジウム及び金、ルテニウム、ロジウム、オスミウム、イリジウム及び白金からなる群から選択される少なくとも１つの金属を含み、金属粒子の量は約0.001〜約8μg/cm2である、電子供与表面を有する基体。該電子供与表面は銀を含み、金属粒子は電子供与表面上に分散された粒子であり、該金属粒子は被覆層を形成しておらず、パラジウム及び金を含む金属粒子には銀が含まれていない基体。【選択図】なし
