Abstract: PURPOSE: A high sensitivity heavy metal detecting sensor using the plasmon resonance of a center-satellite nano structure and a detecting method thereof are provided to amplify a plasmon resonance phenomenon, thereby detecting a trace amount of heavy metal existing in a solution at high sensitivity. CONSTITUTION: A high sensitivity heavy metal detecting sensor using the plasmon resonance of a center-satellite nano structure comprises a supporter(10), a first metal nano particle(20), and a second metal nano particle(30). The first metal nano particle is arranged on the supporter and surface-polished by a first compound(24) including a first functional group(22). The second metal nano particle is surface-polished by a second compound(34) including a second functional group(32). The second metal nano particle is arranged around the first metal nano particle by joining the first and second groups, thereby inducing a plasmonic resonance.
