摘要：

Carboxylic acid-functionalized Au nanoparticles with very small and uniform core size (1.8 nm) could be prepared on the basis of the Brust's two phase method using 11-mercaptounde-canoic acid (MUA) as a surfactant. Various sizes of MUA-protected Au nanoparticles (MUA-Au) were obtained by the heat-treatment method in the solid state from 150 to 170degreesC.
