M. Ozsoz et al., MUSHROOM-BASED COBALT PHTHALOCYANINE DISPERSED AMPEROMETRIC BIOSENSORFOR THE DETERMINATION OF PHENOLIC-COMPOUNDS, Electroanalysis, 8(2), 1996, pp. 147-150
The use of mushroom tissue as a source for polyphenol oxidase for the
determination of phenolic compounds is described. The enzymatic reacti
on between mushroom polyphenol oxidase and phenolic compounds is coupl
ed with the use of cobalt phthalocyanine dispersed in carbon paste. Th
e effects of applied potential to the responses are investigated. Coba
lt phthalocyanine dispersed electrodes give shorter response times and
a lower applied potential compared to conventional tissue biosensors.
