In this study, a photo-bioelectrochemical fuel cell was constructed for photocurrent generation by illuminating the electrodes within an aqueous solution. In this purpose, gold electrode was coated with poly 4-(4H-Dithieno [3,2-b:2′,3′-d]pyrol-4-yl) aniline, P(DTP-Ph-NH2) conductive polymer fi lm by using electrochemical polymerization. Then, P(DTP-Ph-NH2) conductive polymer fi lm coated surface was electrochemically modi fi ed with cytochrome C which covalently linked onto the surface via bis-aniline functionality of the polymer fi lm and formed crosslinked-structure. The thylakoid membrane was a ...Daha fazlası

In this study, gold electrodes (GE) were coated with conducting polymers to obtain a high photocurrent using cyanobacteria from a novel bioelectrochemical fuel cell. For this purpose, 4‐(4H‐ditiheno[3,2‐b:2',3'‐d]pyrol‐4‐yl) aniline and 5‐(4H‐dithieno[3,2‐b:2',3'‐d]pyrol‐4‐yl) napthtalane‐1‐amine monomers were coated on GE by performing an electropolymerization process. After that, gold nanoparticles (AuNP) were specifically modified by 2‐mercaptoethane sulfonic acid and p‐aminothiophenol to attach to the electrode surface. The conducting polymers GE coat was modified with functionalized AuNP ...Daha fazlası
In this study, an amperometric cholesterol biosensor was constructed based on cholesterol oxidase immobilized on a conducting 4-(4H-dithienol[3,2-b:2’,3’d]pyrrole-4)aniline polymer, (DTP(aryl)aniline). Glassy carbon electrodes were covered with P(DTP(aryl)aniline) which is used for the wiring of enzyme to the electrode surface by using electro-polymerization. The electron transfer was successfully made by the bio-catalytic activity and possession of the unique morphology of the polymer allowed efficient immobilization of the cholesterol oxidase enzyme. Analytical performances, linear range, de ...Daha fazlası

Herein, an electrochemical urea sensing bio-electrode is reported that has been constructed by fi rstly electropolymerizing 4-(2,5-Di(thiophen-2-yl)-1H-pyrrol-1-yl)aniline monomer (SNS-Aniline) on Pencil Graphite Electrode (PGE), then modifying the polymer coated electrode surface with di-amino-Ferrocene (DAFc) as the mediator, and lastly Urease enzyme through glutaraldehyde crosslinking. The e ff ect of pH, temperature, polymer thickness, and applied potential on the electrode current response was investigated besides performing storage and operational stability experiments with the interferenc ...Daha fazlası
