Disclosed is a method of preparing a silver nanoparticle-containing functional microcapsule harboring the intrinsic antimicrobial and therapeutic functions of silver, as well as characteristic functions supplied by a functional substance contained in its inner core, which comprises mixing a functional substance such as a perfume with a surfactant in water, and emulsifying the mixture; adding an outer shell-forming substance such as a melanin precondensate to the resulting emulsion to form a microcapsule containing the functional substance in a spherical inner core and having an outer shell; and treating the microcapsule before hardening of the outer shell with silver nanoparticles dispersed in a water-soluble styrene maleic anhydride polymer solution to adhere the silver nanoparticles to the outer shell of the microcapsule.
