A wide range of biologically relevant analytes has been detected through amperometric sensing. Among them, glucose and lactate are crucial target compounds in medicine, sport, nutritional science, and food quality control.
Layered Double Hydroxides (LDHs) have been employed by our research group for more than 25 years to modify conductive supports for the development of electrochemical sensors [1]. They have been mainly used to determine oxidizable analytes exploiting the electrocatalytic properties of Co and Ni centres, but also to entrap oxidase enzymes, with high retention of their activity, to produce amperometric biosensors.
