In this paper the establishment of the a no gallic acid functionality of the nano-gold assembly materials detection of lead ions in the method, the surface of gold nanoparticles did not gallic acid and the lead ion complexation role, led to the distance between the gold nanoparticles changes the rea

This building was a tannic, the nano-assembly materials test lead ion method, and through the surface of the rice was not tannic and lead ions, leading to contact with nano-particles of the distance between changes in Nm, and the response-UV absorption spectroscopy of the particles, which migrate to

This article established one kind to examine the plummet ion using the gallic acid functionalization nanometer golden assembly material the method, through the nanometer gold watch surface gallic acid and the lead ion complexing action, caused between the nanometer golden pellet the distance change,

This established has a using no food child acid function of of nano gold assembled material detection lead ion of method, by Nano gold surface of no food child acid and lead ion of complex-in role, led to nano gold particles Zhijian distance of changes, reaction in Nano gold particles purple outside
