- Cd2+ Mg2+ Cd2+ Mg2+ Cd2+ ION OR Mg2+ ION DETECTION SENSOR COMPRISING METAL NANOPARTICLES OF CORE-SHELL STRUCTURE AND Cd2+ ION OR Mg2+ ION DETECTION METHOD USING THE SAME

摘要

The present invention relates to a Cd^(2+) ion or Mg^(2+) ion detection sensor. The present invention contains metal nanoparticles with a core-shell structure, the core of the metal nanoparticle contains gold (Au), the shell contains silver (Ag), and the metal nanoparticle is modified with a porphyrin-based compound. In the present specification, the sensor capable of quickly and effectively detecting Cd^(2+) ion or Mg^(2+) ion, which is physiologically important ion in a cell, is provided depending on whether the detection sensor changes color or expresses fluorescence.
