Nanoparticles for detecting calcium ions and Colorimetric High-Throughput Screening Method for Pd-Catalyzed Coupling using the same

摘要

PURPOSE: An advanced celadon green screening method for a palladium catalyzed coupling reaction is provided to visually or simply confirm the palladium catalytic cross-coupling reaction of aryl iodide with a UV absorbance conversion rate. CONSTITUTION: An advanced celadon green screening method for a palladium catalyzed coupling reaction includes gold nanoparticles and nucleotide bonded on the surface of the gold nanoparticles. The average diameter of the gold nanoparticles is in a range between 5 and 50nm. The base parts of the nucleotide are covalent-bonded on the surfaces of the gold nanoparticles. The nucleotide is one or more selected from a group including ATP, CTP, GTP, and TTP. The screening method of the palladium catalyst coupling reaction includes a stabilized gold nanoparticle solution and a specimen mixing process and a color change observation process.
