Conducting electroactive

Recent studies performed with deactivated anodes show [55] that electroless or electrolytic platinum deposition on failed anodes, not only lowered the polarisation behaviour of these anodes (see Fig. 5.20), but also demonstrated an equivalent lifetime as that of a new anode in accelerated life tests in the sulphuric acid solution (see Fig. 5.21). These results unequivocally demonstrate that the deactivation of anodes, for which the Ru loading is still high, is a direct consequence of the depletion of Ru from the outer region of the anode coating. Note that this process of surface enrichment by conducting electroactive species will not lead to reactivating a failed anode, if there is a TiC>2 build-up at the Ti substrate/coating interface. 

Electropolymerizable monomers that give rise to conducting electroactive polymers (CEPs) or insulating polymer thin films provide a convenient approach for the immobilization of DNA. More importantly, this method provides an easy means to achieve spatial separation of the ssDNA sequence... 

Another coupling method, i.e. cross-linking or entrapment in polymeric films, which has been used to create a more permanent nucleic acid surface, is described in some chapters (e.g. conductive electroactive polymers for DNA immobilization and self-assembly DNA-conjugated polymers). One chapter reviews the basic characteristics of the biotin-(strept)avidin system laying the emphasis on nucleic acids apphcations. The biotin-(strept)avidin system can be also used for rapid prototyping to test a large number of protocols and...

One challenge within the area of conducting electroactive polymers such as polypyrrole (PPy) is increasing the stability of the materials. By doping PPy with [Co(C2B9Hn)2] , the material becomes more resistant to overoxidation by 300-500 mV. ... 

Components with improved mechanical properties can be produced by mixing the above processable polymers with other polymers. For example, we have mixed conducting polymer colloids with water based latex paints to form conductive, electroactive paints with excellent adhesion to a range of metals [132], Interestingly, the paint-metal adhesion was actually increased by addition of the conducting polymer colloid.
