Bubble electrodeposition of gold porous nanocorals for the enzymatic and non-enzymatic detection of glucose

Au nanocorals are grown on gold screen-printed electrodes (SPEs) by using a novel and simple one-step electro-deposition process. Scanning electron microscopy was used for the morphological characterization. The devices were assembled on a three-electrode ...

Label-Free Electrochemical Detection of MicroRNA-122 in Real Samples by Graphene Modified Disposable Electrodes

Tugba Kilic

In the present work, an electrochemical nucleic acid biosensor has been designed for the purpose of detection of miR-122 in real samples, i.e cell lysates. The fabrication of the biosensor has been done first by immobilization of complemantary anti-miR-122 ...

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

Giovanni De Micheli, Sandro Carrara

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 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, Christian Müller

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 ...

Electrochemical nanostructured biosensors: carbon nanotubes versus conductive and semi-conductive nanoparticles

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Gianluca Piccinini

The aim of this work was to demonstrate that various types of nanostructures provide different gains in terms of sensitivity or detection limit albeit providing the same gain in terms of increased area. Commercial screen printed electrodes (SPEs) were func ...

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

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

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 ...
