“…For above mentioned reasons, a series of biosensors by using surface plasmon resonance [2], electrochemiluminescence [3,4], fluorescence [5,6], colorimetry [7][8][9]and electro-chemistry [10][11][12] have been established for the detection of glucose in the last decades. Among which, electrochemical method is one ofthe routinelyused method because of its merits of good portability, low cost, easy operation and simple instrumentation [13,14].…”
