Gold electrode surfaces, modified

Multipoint attachment of proteins to gold electrode surfaces modified with an alkylthiol SAM... 

Fig. 1.1. (a) SPR angle shifts (A pi) showing the electrostatical adsorption of cytochrome-c on gold electrode surfaces modified with a 3-mercaptopropionic acid SAM (I) after addition of cytochrome-c to a final concentration of ca. 2.5 x 10 M in 5 mM Na-phosphate pH 7.0 (full fine) or in 5 mM Na-phosphate, 100 mM KCl pH 7.0 (dotted line) (11) after rinsing the surface with clean buffer solution, (b) Cyclic voltammograms of a monolayer of cytochrome-c adsorbed on a gold electrode modified with a 3-mercaptopropionic add SAM recorded in 5 mM Na-phosphate, pH 7.0, at 50, 100 and 200 mV s.

Scheme 13. Photochemical switching of electrical interactions of cytochrome-c with a gold electrode surface modified with 4,4 -dip3rridyldisulfide and the electroenz3maatic reduction of oxygen by c3dochrome-c oxidase [261].

Scheme 14. Electrochemically-induced release of biotin from a gold electrode surface modified with a protein-resistant mixed alkylthiol SAM (biotinyl derivative attached to the alkylthiol SAM via a paraquinone moiety) [267],...
