Calixarene Monolayers as Quartz Crystal Microbalance Sensing Elements in Aqueous Solution

Autor: M. T. Cygan, T. D. Dunbar, Collins Ge, C.G. Gibbs, C.D. Gutsche, David L. Allara

Publikováno v: Analytical Chemistry. 71:142-148

We have examined p-tert-butylcalix[4]arenetetrathiolate (BCAT) monolayers for their potential use as molecular recognition elements for in situ aqueous chemical sensors. Spectroscopic and wetting studies of BCAT monolayers on Au{111} reveal that the

Publikováno v: Journal of Physics: Condensed Matter. 10:7703-7712

We discuss how structural domain boundaries, liquid drop boundaries and other topologically one-dimensional features can be used to focus or to define the spatial extent of deposition or chemical reaction. We also show how reactants can be delivered

Publikováno v: Annals of the New York Academy of Sciences. 852:145-168

We have measured the electron transport properties of single and bundled molecules imbedded in crystalline monolayers of alkanethiols self-assembled on Au{111} surfaces. These measurements have been performed using scanning tunneling microscopy and m

Modification of self-assembled monolayers of alkanethiols on gold by ionizing radiation

Autor: Ulrik Gelius, T. D. Dunbar, Mikael Wirde, David L. Allara

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 131:245-251

Self-assembled films of octadecanethiols on polycrystalline Au have been studied with monochromated X-ray photo-electron spectroscopy (XPS). The focus has been on the SAu interface. It is demonstrated that ionizing radiation causes breaking of S�

Molecular Scale Electronics. Critical Nanolithography Issues of Synthesis and Addressing

Publikováno v: MRS Proceedings. 584

As we rapidly approach the point at which solid-state electronic devices cease to be made any smaller, molecular scale electronics offers, perhaps, the best chance for a continued miniaturization of computational devices. We must, however, completely
