Single Cell Force Spectroscopy was combined with Electrochemical-AFM to quantify the adhesion between live single cells and conducting polymers whilst simultaneously applying a voltage to electrically switch the polymer from oxidized to reduced states. The cell-conducting polymer adhesion represents the non-specific interaction between cell surface glycocalyx molecules and polymer groups such a...

Many research studies have been conducted on the use of conjugated polymers in the construction of chemical sensors including potentiometric, conductometric and amperometric sensors or biosensors over the last decade. The induction of conductivity on conjugated polymers by treating them with suitable oxidizing agents won Heeger, MacDiarmid and Shirakawa the 2000 Nobel Prize in Chemistry. Common...

The π-conjugated backbone conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT) is chemically doped to the conducting regime (σ ~ 30 S/cm) with poly(4-styrenesulfonate) (PSS). Construction of an all polymer FET is described and the time dynamics of a simple polymer channel device using aluminum as the gating material is discussed. On/off ratios approaching 10 are achieved but with relativ...

UNLABELLED The use of biomolecules as oxidants for the synthesis of conducting polymers provides an important tool for the control of polymer properties. Using PEDOT PSS as a representative conducting polymer, we compare a set of heme proteins (soybean peroxidase, cytochrome c, and horseradish peroxidase) used as oxidants. The resulting PEDOT PSS was characterized with visible and near IR s...

The paper presents and discusses a method to achieve beneficial electrochemical effects mediated by interfaces in an ionic conducting polymer matrix. The beneficial effects include enhanced ionic transport, catalysis of anodic oxidation reaction, and stabilization of the lithium-electrolyte interface in lithium-based electrochemical cells. Polyethylene oxide (PEO) doped with LiN(SO2CF2CF3)2 (Li...
