“…At higher potential the de pendence is less dramatic. In accordance with previous results [14,16,27] we found that at a potential of 100 mV versus Ag/AgCl reference the current due to the addition of glucose still resulted in a positive current response, whereas the deliberate addition of a small amount of hydrogen peroxide (0.0025 wt.%) resulted in a strongly negative response [28][29][30]. This experiment shows that the response to glucose must be the result of direct electronic contact between the enzyme mol ecules and the conducting polymer indicating that ox ygen mediation is not an important mechanism (see also below).…”

A biosensor based on a conducting screen-printing ink for the direct amperometric measurement of glucose is described. Carbon electrode prints, containing the work, reference and auxiliary electrodes, are used as the substrate for the sensor. The active parts of the carbon ink are the redox enzyme glucose oxidase and the conducting polymer poty(pyrrole), which can communicate directly with each other. As a result, the biosensor is largely independent of the oxygen concentration. The feasibility of the described biosensor ink for screen printing is shown.

“…Chemical template synthesis can be accomplished by simply immersing the membrane into a solution of the desired monomer and its oxidizing agent (7,11,33). Such methods have since been used by other groups (34)(35)(36)(37).…”

Materials with nanoscopic dimensions not only have potential technological applications in areas such as device technology and drug delivery but also are of fundamental interest in that the properties of a material can change in this regime of transition between the bulk and molecular scales. In this article, a relatively new method for preparing nanomaterials, membrane-based synthesis, is reviewed. This method entails synthesis of the desired material within the pores of a nanoporous membrane. Because the membranes used contain cylindrical pores of uniform diameter, monodisperse nanocylinders of the desired material, whose dimensions can be carefully controlled, are obtained. This "template" method has been used to prepare polymers, metals, semiconductors, and other materials on a nanoscopic scale.

“…For example, recent work has shown that FADH 2 can give its electrons directly to the doped form of polypyrrole; i.e. a mediator is not necessary (30). We have recently developed an interfacial polymerization method to synthesize ultrathin film composite membranes based on polypyrrole and its derivatives (3).…”
