Photoinduced redox cycle of riboflavin at a water/oil interface.

Using Boehmite Nanoparticles as an Undercoat, and Riboflavin as a Redox Probe for Immunosensor Designing: Ultrasensitive Detection of Hepatitis C Virus Core Antigen

In this study a label-free electrochemical Immunosensor for ultrasensitive detection of Hepatitis C virus core antigen in serum samples was fabricated by using a simple approach. In this method a low-cost and sensitive immunosensor was fabricated based on a boehmite nanoparticles (BNPs) modified glassy carbon. The BNPs provide a specific platform with increased surface area which is capable of ...

An Experimental Investigation of Water Effects on Asphaltene Surface Behavior through Interfacial Tension Measurements

As a physiochemical property, asphaltenes are known to be one the most surface active compounds in crude oil. Due to such property, their behavior is most probably influenced by fluid-fluid interactions at the contact surface (interface). Potentially and naturally, in most cases, water is in contact with crude oil and is co-produced with it as well. Considering that asphaltene molecules are pol...

Characterization Study for Nanocompositions of Methylene Blue and Riboflavin-Nafion on the Electrode Surface

     Nafion is a perfluorinated anionic polyelectrolyte. The increasing popularity of nafion for the fabrication of redox polymer modified electrodes in recent years arises from easy fabrication, good electrical conductivity and high partition coefficients of many redox compounds in nafion. To investigate the production of nano-compositions by mixing electron transfer material and nafion polyme...

Electro-Coalescence of an Aqueous Droplet at an Oil–Water Interface with an Investigation of Secondary Droplets Formation

Self-assembly and redox induced phase transfer of gold nanoparticles at a water-propylene carbonate interface.

Citrate-stabilized gold nanoparticles were found to spontaneously self-assemble into a lustrous film at a bare water-propylene carbonate interface after vigorous shaking, due to the extremely low interfacial tension. The presence of an electron donor, tetrathiafulvalene, in the oil phase, led to the extraction of particles into the organic phase.
