| The electrochemical biosensors have been extensively investigated for the determination of a wide variety of analytes. Electrochemical biosensors have a fast response time and easy to miniature. However, the interference with similar analogs hampers the application of electrochemical biosensor. The optical biosensor can minimized such drawbacks. In this study, we successfully incorporated the electrochemical and optical biosensors into one chip which have a high efficiency for the detection of multianalytes at a time. A screen-printing electrode coupled with a microfluid system was fabricated as an electrochemical biosensor which enzymes were encapsulated in sol-gel derived TiO2 materials as an optical biosensor. Bilirubin, urea, creatinine and uric acid were selected as target compound. Little cross reactivity was found for the tested compounds. The analytical performance of the dual transducer biosensors for different analytes were determinated and compared in this study. |
