| Abstract(in English) | Recent work on gold nanoparticles has flourished in the past few years, as a result of development of several methods to control the particle size and to stabilize the particles in solution. More, considerable attention focuses on the possibility of nanoparticles assembly because of their important physical, electronic, optical properties, and of potential applications for electronic circuit components of extraordinary high integration. Among various patterning strategies have been developed to create characteristic ordered nanostructures of gold nanoparticles, herein we report a new methodology for a reversible self-assembly of gold nanoparticles bearing β-cyclodextrins, which was constructed by potential-controlled adsorption onto Au(111) surfaces in sodium perchrolate solution. The gold nanoparticles adsorb randomly on Au(111) at a positive potential of more than 0V vs. SCE. On the other hand, a cohesive structure of the particles is observed at the range of a potential from -0.6 to 0V vs. SCE, due mainly to weaken adsorption of the particles, resulting intermolecular interaction of the β-cyclodextrin substituted onto the gold nanoparticles. |
