Abstract
Provided is a method of preparing composite nanoparticles, which includes: a) preparing a metal nanocore having a nano-star shape from a first reaction solution in which a first metal precursor is mixed with a first buffer solution; b) fixing a Raman reporter in the metal nanocore; and c) forming a metal shell, which surrounds the nanocore in which the Raman reporter is fixed, from a second reaction solution in which the nanocore in which the Raman reporter is fixed, and a second metal precursor are mixed with a second buffer solution.
