Microgravimetric quartz-crystal microbalance analysis of cytochrome c interactions with pyridine and pyridine-nitrospiropyran monolayer electrodes: characterization of inter-protein complexes at the functionalized surfaces
Autor: Mazzi Lion-Dagan, Itamar Willner, Iddo Z. Ben-Dov
Publikováno v: Colloids and Surfaces B: Biointerfaces. 8:251-260
The association of cytochrome c (Cyt. c) to a pyridine monolayer assembled onto Au electrodes associated with a quartz crystal is followed microgravimetrically using a quartz-crystal microbalance (QCM). The association constant of Cyt. c to the monol

pH-switched electrochemistry of pyrroloquinoline quinone at Au electrodes modified by functionalized monolayers
Autor: Mazzi Lion-Dagan, Eugenii Katz, Itamar Willner
Publikováno v: Journal of Electroanalytical Chemistry. 408:107-112
Gold electrodes were modified with thiolate monolayers that included dissociative groups of different p K a values: cystamine, 4-aminothiophenol and 4-pyridyl disulfide. The electrochemistry of the redox probe pyrroloquinoline quinone (PQQ) was exami

Amperometric Transduction and Amplification of Optical Signals Recorded by a Phenoxynaphthacenequinone Monolayer Electrode: Photochemical and pH-Gated Electron Transfer
Autor: Moshe Portnoy, Amihood Doron, Itamar Willner, Mazzi Lion-Dagan, Eugenii Katz
Publikováno v: Journal of the American Chemical Society. 118:8937-8944
A phenoxynaphthacenequinone photoisomerizable monolayer was assembled onto an Au electrode. The resulting “trans”-quinone monolayer exhibits poor electrochemical reversibility due to a nondensely-packed configuration. Treatment of the trans-quino

Control of electrochemical processes by photoisomerizable spiropyran monolayers immobilized onto Au electrodes: amperometric transduction of optical signals
Autor: Mazzi Lion-Dagan, Eugenii Katz, Itamar Willner
Publikováno v: Journal of Electroanalytical Chemistry. 382:25-31
Photoisomerizable self-assembled spiropyran (SP) monolayers on Au electrodes provide a means of transducing optical signals recorded by the monolayers as amperometric responses. An SP-modified monolayer on a Au electrode photostimulated the redox com

PHOTOREGULATION OF α-CHYMOTRYPSIN ACTIVITY IN ORGANIC MEDIA: EFFECTS OF BIOIMPRINTING
Autor: Peter Bäuerle, Shai Rubin, Franz Effenberger, Itamar Willner, Johann Wonner, Mazzi Lion-Dagan
Publikováno v: Photochemistry and Photobiology. 59:491-496
alpha-Chymotrypsin exhibits photoswitchable activities in an organic solvent after covalent modification of the protein backbone with thiophenefulgide active ester (2). The thiophenefulgide-modified alpha-chymotrypsin exhibits reversible photoisomeri

Photostimulation of dinitrospiropyran-modified glucose oxidase in the presence of DNP-antibody-A biphase-switch for the amperometric transduction of recorded optical signals
Autor: Mazzi Lion-Dagan, Eugenii Katz, Itamar Willner
Publikováno v: Chemical Communications. :623
A dinitrospiropyran-modified glucose oxidase monolayer electrode in the presence of DNP-Ab acts as a diphasic switch for amperometric transduction of recorded optical signals.
