The present invention relates to an aqueous antimicrobial composition in which nanosilver is contained in silica nanotubes; wherein, in use, the aqueous antimicrobial composition is mixed with an aqueous base composition such as a water-based paint, a ceramic composition or a fibre coating composition immediately prior to use, thereby giving the advantage that nanosilver oxidizing reactions are limited since the time spent in contact with organic solvent(s) contained in the aqueous base composition is shortened, and also that the antimicrobial performance is improved due to an outstanding dispersion force since, unlike silica having a spherical structure, the nanotube structure ensures that the nanosilver particles themselves do not undergo coagulation or the like in any type of aqueous solvent.

Further, as silver nanoparticles are synthesized at room temperature and atmospheric pressure by utilizing the silica nanotube, the cost of synthesizing silver nanoparticles is remarkably reduced as compared to conventional methods for synthesizing silver nanoparticles, which enables mass production. Further, silver nanoparticles have a high sterilizing capability and a high antibacterial activity, and a high solvent resistance to alcohol, acid, alkali, pure water and the like, which enables silver nanoparticles to be applied to a wide variety of application fields.
