Fabrication of designed architectures of Au nanoparticles on solid substrate with printed self-assembled monolayers as templates
(2000)
This paper provides a convenient method for fabricating architectures of Au nanoparticles on solid substrate,with precise position and density control. Our strategy is to modify Au substrate with self-assembled monolayers ...
Discrimination of dendrimer aggregates on mica based on adhesion force : a pulsed force mode atomic force microscopy study
(2000)
Two different types of aggregated polyphenylene dendrimer molecules, G2Td(COOH)16 and G4-Td, obtained by spin coating a dilute solution onto freshly cleaved mica surfaces, and their adhesion properties were measured by ...
Fabrication of microelectrode arrays using microcontact printing
(2000)
Geometrically defined gold microelectrode arrays are fabricated, in which a self-assembled monolayer of hexadecylmercaptan acts as passivation layer and is region-selectively formed by microcontact-printing (μCP). By use ...
Atomic force microscopy evidence of citrate displacement by 4-mercaptopyridine on gold in aqueous solution
(2000)
The displacement adsorption process of 4-mercaptopyridine (4-MP) on trisodium citrate preadsorbed gold surface in aqueous solution was studied using atomic force microscopy (AFM). The measurement was done by monitoring the ...
Properties of single dendrimer molecules studied by atomic force microscopy
(2000)
Well-separated, individual polyphenylene dendrimer molecules have been prepared by spin coating on a mica surface, and subsequently imaged by noncontact atomic force microscopy (NCAFM). The observed height is in good ...
Demonstration of high-resolution capability of chemical force titration via study of acid/base properties of a patterned self-assembled monolayer
(2000)
An experimental approach for probing the resolution of chemical force titration is reported here. A self-assembled monolayer (SAM) patterned with COOH and CH3 groups was used as the model surface, and its local dissociation ...
