Dielectrophoresis of lambda-DNA using 3D carbon electrodes

Philippe Renaud, Rodrigo Martinez Duarte

Carbon electrodes have recently been introduced as an alternative to metal electrodes and insulator structures for dielectrophoretic applications. Here, an experimental and theoretical study employing an array of 3D carbon electrodes contained in a microfl ...

A Current-Mode Potentiostat for Multi-Target Detection Tested with Different Lactate Biosensors

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Seyedeh Sara Ghoreishizadeh

Real-time and multi-target detection by wireless implantable devices is of increasing interest for chronic patients. In this work, electrode sharing is proposed to minimize the size of the implantable device when several three-electrode-based sensing sites ...

Near infrared electrochromism of doped colloidal nanocrystals

Raffaella Buonsanti, Anna Llordes Gil

Electronically doped metal oxide nanocrystals, such as indium tin oxide (ITO) and aluminum-doped zinc oxide (AZO) exhibit surface plasmon absorption in the near IR (NIR). In addn., chem. strategies have been developed for achieving conducting networks of n ...

Electrochemical aspects of display technology based on nanostructured titanium dioxide with attached viologen chromophores

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt

Progress in recent years in the field of electrochromic displays based on viologen modified high-surface area TiO2 electrodes (Vio2+/TiO2) has moved the technol. towards commercialization. Viologen mols. (Vio2+), derivatized with phosphonic acid attachment ...
