Optimized Electrochemical Detection of Anti-Cancer Drug by Carbon Nanotubes or Gold Nanoparticles

Giovanni De Micheli, Sandro Carrara, Nima Aliakbarinodehi

Nanostructured biosensors with the aim of electroactive cancer-drug detection were investigated. The aim of this work is improvement of the sensitivity and limit of detection of two differently nanostructured biosensors to find out the best choice for quan ...

Interplay between the potential waveform and diffusion layer dynamics determines the time-response of voltammetric detection in microchannels

Martinus Adela Maria Gijs, Raphaël Etienne Jean Trouillon

The diffusion layer is a critical factor affecting the temporal response of electrochemical devices. In this article, we have investigated the effect of the relaxation of the diffusion layer during the potentiodynamic sensing of ferrocenemethanol (FcMeOH) ...

Faradic Peaks Enhanced by Carbon Nanotubes in Microsomal Cytochrome P450 Electrodes

Giovanni De Micheli, Sandro Carrara, Camilla Baj-Rossi

In this work we present an investigation on the behavior of microsomes containing human cytochrome P450 in cyclic voltammetry for drug detection. The microsomes are adsorbed on the surface of multi-walled carbon nanotubes by drop-casting. We demonstrate th ...

Gas-phase volatile organic chloride electroreduction: A versatile experimental setup for electrolytic dechlorination and voltammetric analysis

Christos Comninellis

Silver is a well-known and largely studied electrocatalytic material for (hydro)dehalogenation reactions of organic halides, a class which includes several priority pollutants. Silver nanoparticles are particularly attractive since exhibit similar or even ...

Precise Control of Intramolecular Charge-Transport: The Interplay of Distance and Conformational Effects

Jacques-Edouard Moser, Lars-Hendrik Mewes, Mateusz Barnaba Wielopolski

A new series of donor–bridge–acceptor (D–B–A) compounds consisting of π-conjugated oligofluorene (oFL) bridges between a ferrocene (Fc) electron-donor and a fullerene (C60) electron-acceptor have been synthesized. In addition to varying the length of the b ...

Decreasing the size of printed comb electrodes by the introduction of a dielectric interlayer for capacitive gas sensors on polymeric foil: Modeling and fabrication

Nico de Rooij, Danick Briand, Francisco Molina Lopez

In this work we present a novel strategy to fabricate printed comb electrodes devices with decreased size by the introduction of a thin dielectric layer between the two combs. The electrical insulation of the two polarities prevents short-cuts occurring be ...
