The present invention relates to a surface-modified nanoparticle and a sensor for detecting colorimetric of zinc ion (Zn 2+ ) using the same. More particularly, the present invention relates to silver nanoparticles (AgNPs) having a diameter of 100 nm or less, ) Is included in the colorimetric detection sensor, zinc ions in environmental pollutants, pharmaceuticals, foods, fuel cells and secondary batteries can be detected more easily than in the prior art. When an ionic surfactant is additionally added to the colorimetric detection sensor, And more particularly, to a colorimetric detection sensor having high selectivity and sensitivity to zinc ions, which can further improve brightness, stability of particles, and reaction speed. |
