This study focuses on the development of a flow injection analysis method that performs nonenzymaticglucose measurement. It is aimed to develop a more economical blood glucose monitoring system bymeasuring the instant blood glucose level indirectly with borate based ion selective electrode. A nonenzymatic electrode based on carbon nanotube-silver borate (CNT-SB) composite electrode wasdeveloped and integrated into a flow injection analysis system as a detector, and glucose measurementwas performed. Potentiometric measurement was made with this detection chamber. Heights ofpotentiometric peaks obtained were used for the determination of the amount of glucose in bloodsamples. Repeated injections were tested by using a mini-sized separation column as stationary phaseand successful results were obtained. In addition, boronic acid solution was used as a carrier solution inthe system, and it is predicted to be more accessible and simple method than the present non-enzymaticmethods as it has ability at neutral pH conditions. The developed glucose measurement system wassimple, economic and fast.
