Self-assembly of polypeptide/pi-conjugated polymer/polypeptide triblock copolymers in rod-rod-rod and coll-rod-coil conformations

Mohamad Hojeij, Raffaele Mezzenga

Self-assembly in the bulk of a series of hybrid triblock copolymers formed by a poly(9,9-dihexylfluorene-2,7-diyl) (PHF) middle block and two poly(gamma-benzyl-L-glutamate) (PBLG) end blocks has been studied. Since the alpha-helical secondary structure of ...

H2O2 generation by decamethylferrocene at a liquid | liquid interface

Hubert Girault, Anne-Clémence Corminboeuf, Michel Prudent, Bin Su, Mohamad Hojeij, Raheleh Partovi Nia, Zdenek Samec

Hydrogen peroxide generation at a liquid|liquid interface occurs with a yield of 20 % with respect to the concentration of reducing agent (decamethylferrocene). The liquid|liquid interface supplies electrons from the reducing agent and protons from the aqu ...

Porphyrin ‘‘Mille-Feuilles” photo-electrodes

Hubert Girault, Bin Su, Mohamad Hojeij

A porphyrin ‘‘Mille-Feuilles” photo-electrode is fabricated layer-by-layer by deposition of anionic [zinc meso-tetrakis(p-sulfonato phenyl) porphyrin]4- (ZnTPPS4−) and positively charged polypeptides on a 11-mercaptoundecanoic acid-modified gold electrode ...

SECM photography

Hubert Girault, Fernando Cortes Salazar, Bin Su, Mohamad Hojeij

A novel strategy for imaging commercial black-and-white negative photo films by scanning electrochemical microscopy (SECM) is demonstrated. The imaging is based on using IrCl3 6 as the redox mediator to dissolve silver grains. The SECM probe is biased at a ...

3D-ITIES supported on porous reticulated vitreous carbon

Hubert Girault, Bin Su, Mohamad Hojeij, Nicolas Eugster

A thin aqueous film prepared by layer-by-layer assembly of oppositely charged polypeptides on 4-aminobenzoic acid modified porous reticulated vitreous carbon (RVC) electrodes was used with the aim of forming a 3D-ITIES. The film containing a redox mediator ...

CdSe Sensitized Thin Aqueous Films: Probing the Potential Distribution Inside Multilayer Assemblies

Hubert Girault, Bin Su, Mohamad Hojeij, Nicolas Eugster

Ultrathin polypeptide multilayer films are assembled by the sequential electrostatic adsorption of monolayers of poly-L-lysine and poly-L-glutamic acid onto carboxylic acid terminated alkanethiol-modified gold surfaces. The polypeptide multilayer films are ...
