Figure 8From: Nano- and microsized zeolites as a perspective material for potentiometric biosensors creation Calibration curves of biosensors. They were based on immobilized BuChE (a) and urease (b), without zeolite (1) and with different heat-treated zeolite Beta: BEA-1 (1), BEA-2 (2), and BEA-3 (3). Measurements were conducted in 5 mM phosphate buffer, pH 7.4. The data shown represent the averaged response of five to seven different sensors.Back to article page
