SELECTIVE DETECTION AND ASYMMETRY DISCRIMINATION OF AMINO ACIDS USING HYDROXY ACID REDUCED GOLD NANOPARTICLES BY COLOR CHANGE

摘要

To solve a problem in conventional gold nanoparticles that they cannot perform selective detection and asymmetry discrimination of amino acids.SOLUTION: The present invention is related to an amino acid detection agent comprising hydroxy acid reduced gold nanoparticles, where the hydroxy acid is a hydroxy acid or a salt thereof and has an asymmetric carbon center: and the amino acid has an NHgroup or an SH group in its side chain.SELECTED DRAWING: Figure 1
