    • A nanoparticle for peptide separation and a preparation method thereof are provided to rapidly and selectively separate desired peptide through a simple process owing to magnetic nanoparticles of which the surface is coupled with a first functional group which selectively reacts to a certain peptide. A nanoparticle for peptide separation has the magnetic surface which is coupled with a first functional group having thiol selectivity. The nanoparticle for peptide separation selectively couples with the peptide including cysteine. The first functional group includes 2-pyridyl disulfide residual group. The magnetic nanoparticle is coated with a silica layer. The first functional group is bonded with the silica layer. The surface of the nanoparticle additionally contains a second functional group which prevents the coherence of the nanoparticles.
