n 2b) ANSWER
Optimisation of the screen printed Electrode the loadings of the electrocatalyst and the Enzyme can be varied. In a study conducted Crouch et al, using chronamperometry, It has been found that the maximum linear range can be acheived with a CoPC loading of 20% m/m relative to the mass of carbon employed in the manufacturing process and a glucose oxidase loading of 628 U per gram of carbon. Optimal operating potential was found to +0.5v following an incubation period of 60s. Additionally an optimum supporting electrolyte was found to be 0.05M Phosphate buffer at pH of 8 which resulted in a linear range of 0.2 to 5mM.
Sensitivity was deemed to be 1.12uA mM^-1 at an optimal operating temperature of 40 degree celsius.
