The present invention provides a metal nanoparticle that is surface-modified with a hydrophilic or hydrophobic functional group, and a composition for optical detection comprising the same. The surface-modified nanoparticles according to the present invention form clusters suitable for optical detection, for example, suitable as an X-ray contrast agent, and have surface plasmon energy in the visible region, thereby being usefully applied to a variety of optical detection methods.
