Kontrollierte Mesostrukturierung und Biofunktionalisierung von Gold zur Erhöhung der Elektroaktivität

Abstract

Redoxreaktionen spielen in der Biochemie eine wichtige Rolle und werden häufig durch Dehydrogenasen und Oxidoreduktasen katalysiert.[1] Dies gilt nicht nur für phy-

Enhanced Light Harvesting in Plasmonic Dye‐Sensitized Solar Cells by Using a Topologically Ordered Gold Light‐Trapping Layer

“…The surface plasmon resonance (SPR) of gold is widely used in the fields of biochemistry and physics, [18][19][20][21][22] enabling to localize irradiated light and extend the optical path length. These aspects are of interest for applications in DSSCs.…”

Electrocatalysis Using Porous Nanostructured Materials

“…Thereafter, porous platinum structures were reported to grow by hydrothermal treatment of these substrate for 10 h at 100 8C using autoclaves containing ethylene glycol, a platinum salt (H 2 PtCl 6 ), and HCl, for example. [53] Nanostructured (mesoporous) electrodes of metals such as Pt [54,55] and Au [56,57] can also be synthesized by electrochemical deposition through electroreduction of a metal salt in the presence of hard or soft templates, such as silica colloids, [56,57] polystyrene (PS) particles, [57] or micelles of octaethylene glycol monohexadecyl ether (C 16 EO 8 ) [54,55] (see Section 2.1). Moreover, ruthenium oxide [58] was synthesized in a similar way; however, in this case, the structure-directing agent was polystyrene.…”

Nanostructuring of Patterned Microelectrodes To Enhance the Sensitivity of Electrochemical Nucleic Acids Detection

“…We show that the production of nanostructured features on electrode surfaces is essential for the performance of the microelectrodes as ultrasensitive electrochemical detectors. A variety of studies have suggested that nanostructures are highly beneficial for biosensing applications because of the increased surface area, enhanced delivery of amplification agents, or precise biomolecule-electrode connections that are possible; [11][12][13][14][15] however, the role of nanostructuring in modulating biodetection sensitivity has not previously been addressed directly.…”
