Abstract
Provided is a method of preparing Raman-active 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 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 a second metal precursor is mixed with the nanocore in which the Raman reporter is fixed. The Raman reporter has a binding affinity for each of a first metal of the metal nanocore and a second metal of the metal shell.

A method of preparing Raman-active nanoparticles, the method comprising:
- 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 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 a second metal precursor is mixed with the nanocore in which the Raman reporter is fixed,
- wherein the Raman reporter has a binding affinity for each of a first metal of the metal nanocore and a second metal of the metal shell.
Raman-active nanoparticles comprising:
- a metal nanocore having a nano-star shape;
- a self-assembled monolayer comprising a Raman reporter fixed in the metal nanocore;
- and
- a metal shell surrounding the self-assembled monolayer,
- wherein the Raman-active nanoparticles have a protruding structure due to the nano-star shape of protrusions.
