摘要：

A cheap amperometric and optical sensor for glucose, based oil an ITO electrode coated with electrodeposited Co/Al hydrotalcite (HT) is described. Cobalt based HT shows a reversible electrochromic behavior which can be exploited for the development of an optical sensor. Working in the optical mode, the linearity range of the sensor is between 0.008 and 0.13 mM with a sensitivity of 1.14 mM(-1) . cm(-2), whereas when working in the amperometric mode, the linearity ranges from 0.002 to 1.5 mM with a sensitivity of 4.24 x 10(-4) A . mM(-1) . cm(-2). The sensor has been successfully employed for the determination of glucose in a serum sample.
