COLORIMETRIC DETECTION SENSOR FOR AURIC ION USING GOLD NANOPARTICLES MODIFIED WITH CHITOSAN DERIVATIVE AND COLORIMETRIC DETECTION METHOD

摘要

The invention gold ions masking agents (masking agent) has a shielding function for the interference ions which interfere with the ion detection chitosan derivative (chitosan derivative) the gold nano-modified by a particle (gold nanoparticle), and gold (Au ³⁺⁾ (Au ⁺³⁾ relates to colorimetric detection sensor and method for the colorimetric detection, and more particularly through the colorimetric detection color changes of the sensor solution of medicine, food, or the like contained in biological samples and drinking water on the dissolved gold (Au ³⁺ ) it is possible to easily detect, to increase the gold ions detected without interference from interfering ions effect even when there is interference ions are contained, and also gold ion (Au ³⁺⁾ for utilizing the selectivity, sensitivity and quantification is excellent And a colorimetric detection method using the same.
