Özet

In this study the biosensor was constructed by immobilizing tissue homogenate of banana peel onto a glassy carbon electrode surface. Effects of immobilization materials amounts, effects of pH, buffer concentration and temperature on biosensor response were studied. In addition, the detection ranges of 13 phenolic compounds were obtained with the help of the calibration graphs. Storage stability, repeatability of the biosensor, inhibitory effect and sample applications were also investigated. A typical calibration curve for the sensor revealed a linear range of 1080 μM catechol. In reproducibility studies, variation coefficient and standard deviation were calculated as 2.69%, 1.44 × 10-3 μM, respectively. © 2010 Informa UK Ltd.
