Abstract:
This work investigated a simple transparency sheet-based colorimetric detection using modified silver nanoparticles (AgNPs) for the determination of calcium (II) ion (Ca2+) in urine samples. 4-Amino-6-hydroxy-2-mercaptopyrimidine monohydrate (AHMP) was used to modify the AgNPs surface, exhibiting extremely change color from yellow to brown in the presence of Ca2+. Upon addition of Ca2+ to the AHMP-modified AgNPs solution, a color change can be clearly observed by naked eyes within 1 minute and the color intensity can be measured by image J software as a result of the aggregation of AgNPs. To verify a complete self-assembly of the AHMP onto the AgNPs surface, the modified AgNPs were characterized using ultraviolet-visible spectroscopy (UV-vis) and Zeta potential. In addition, various parameters affecting on the Ca2+ determination including the modifier volume ratio, pH, incubation time, reagent ratio and interferences were investigated. With this proposed method, under the optimal conditions, a quantitative linearity was established in the range of 1-10 mM (R2 = 0.9866) with the detection limit of 0.74 mM. Overall, this work may afford a feasible, fast approach for detecting and monitoring the Ca2+ levels for hypercalciuria, hypocalciuria, and calcium supplementation because the simplicity in operation and instrumentation of the colorimetric device.
