Polymeric phthalocyanine films prepared from 51a have been investigated as electrocatalysts, in biological applications and as amperometric biosensors [157]. The electropolymerized films exhibited better activities than analogous low molecular weight phthalocyanine films. Some examples are given ... 

Electrochemical polymerization (electropolymerization) has been recognized as a useful technique for the preparation of pinhole-fiee membranes (1,2) that have found numerous applications in electrocatalysis, amperometric biosensors, etc. These membranes are prepared by the electrodeposition of a polymeric film on the surface of an electrode that is immer in a solution of an appropriate monomer. In order for polymerization to occur, groups that can be electrochemically oxidized or reduced to form a polymer need to be present in the monomer.

As was mentioned earlier, negatively charged CNTs can act as counterions in the electrochemical deposition of ECPs [19]. This straightforward method has been used for preparation of amperometric enz mie electrodes via entrapment of the enz3mie in the resulting ECP-CNT composite [63, 64]. Wang et al. developed amperometric glucose biosensors based on the PPy-MWCNT-GOD composite [63]. The composite was prepared by a simple one-step electrochemical method in which p3U role was electropolymerized at a constant potential of 0.7 V in the presence of c-MWCNTs and GOD. Results from the CV measurements showed that the incorporated c-MWCNTs act as counterions that maintain the electrical neutrality of the film. The influence of different parameters, such as the amount of the used MWCNTs, and the...
