Özet

The use of mushroom tissue as a source for polyphenol oxidase for the determination of phenolic compounds is described. The enzymatic reaction between mushroom polyphenol oxidase and phenolic compounds is coupled with the use of cobalt phthalocyanine dispersed in carbon paste. The effects of applied potential to the responses are investigated. Cobalt phthalocyanine dispersed electrodes give shorter response times and a lower applied potential compared to conventional tissue biosensors.
