METHOD FOR EVALUATION OF SOLUTION CHARACTERISTICS USING ORGANIC MATERIAL-AU NANOPARTICLE CONJUGATES, AND APPARATUS FOR THE SAME

摘要

PURPOSE: A method and apparatus for evaluating solution characteristic using organic material-gold nanoparticle conjugate are provided to confirm detection of metal ion. CONSTITUTION: A method for evaluating solution characteristic using organic material-gold nanoparticle conjugate comprises: a step of preparing a solution containing organic material-gold nanoparticle conjugate; and a step of providing alkali metal ion in the solution to form nanoparticle assembly. The organic material-metal nanoparticle conjugate contains dipotassium bis(p-sulfoatophenyl)phenyl phosphine adhered gold nanoparticles. The alkali metal ion is lithium ion, sodium ion, potassium ion, or rubidium ion. An apparatus for evaluating solution characteristic using the organic material-gold nanoparticles comprises: a sample unit having the organic material-gold nanoparticle conjugate; and an optical unit for measuring sample absorbance.
