金属ナノコロイドを用いた非溶出型抗菌・抗ウイルス剤の開発

抄録

In recent years, with the improvement of quality of life, there has been an increasing interest in aseptic

condition in various fields, including the residential environment. This review outlines the research and

development status of antimicrobial and antiviral materials that have been undertaken to date. Then, the

antimicrobial and antiviral material, such as ABCoat consisting of metallic nanocolloids, which we have been

developing with focusing on safety is presented.

ABCoat is an aqueous dispersion in which platinum and silver are nanocolloidated, and the constituent

concentration of the particles is 0.1wt% or less, and the average particle diameter is about 100nm. By

supporting this dispersion on various materials, the Ag+ and Pt4+ derived from metal nanocolloids don’t elute

and represents antimicrobial performance. In a short time, ABCoat reduces microbes such as Escherichia

coli, Staphylococcus aureus, herpes simplex viruses, and adenoviruses. This mechanism of action may be

inactivation by adsorption of nanoparticles to surface of bacteria and viruses.
