abstract the graphene–chitosan composite film modified glassy carbon electrode was fabricated and used to determine amlodipine besylate. in 0.1 m ph 7.3 phosphate buffer solutions, the redox peak currents of amlodipine besylate increased significantly at graphene–chitosan composite film modified glassy carbon electrode compared with bare electrode and chitosan modified glassy carbon electrode, ...

Redox conditions in natural waters are a fundamental control on biogeochemical processes and ultimately many ecosystem functions. While the dioxygen/water redox couple controls redox thermodynamics in oxygenated aquatic environments on geological timescales, it is kinetically inert in the extracellular environment on the much shorter timescales on which many biogeochemical processes occur. Inst...

    Electrochemical aptamer-based sensors attract a lot of interest as useful methods because of their low cost, accuracy, sensitivity, and simplicity. An electro-active redox molecule comprises the main part of the electrochemical-based sensors. Ferrocene is one of the most popular redox molecule used in biosensor fabrication. But, instability of ferrocenium ion in strong nucleophilic reagents...

Titania particles modified with an extremely small amount (<0.01 mol%) of a rhodium species exhibited photocatalytic activity for the oxidative decomposition of acetaldehyde in air under visible-light irradiation. The reaction proceeded via a two-photon band-gap excitation mechanism resembling the Z-scheme with an external redox couple, using a built-in Rh(iii)-Rh(iv) redox couple.

AIMS Morphine signaling via the μ-opioid receptor (MOR) is coupled to redox-dependent zinc release from endogenous stores. Thus, MOR activation stimulates the complex formed by RGSZ2 (a regulator of G protein signaling) and neural nitric oxide synthase (nNOS) to produce NO, and to recruit PKCγ and Raf-1 in a zinc-dependent manner. Accordingly, we investigated whether redox regulation of zinc me...

The redox state, like the pH or the osmotic pressure, represents chemical characteristics of the intracellular environment. The intracellular redox homeostasis can be disturbed by the installation of the “oxidative stress”, which manifests itself through the dysregulation of the balance between the systems that produce oxidant agents and the antioxidant defense mechanisms (the redox balance). E...
