Development of Voltammetric Urea Sensors Based Poly(3-methylthiophene) film

Poly(3-methylthiophene)막 위에 urease를 고착시킨 Voltammetric Urea Sensor의 개발

Urea is detected as an indicator of renal disease in the human body. For these reasons, many biosensors for urea have been developed based on the enzymatic reaction of urea hydrolysis catalyzed by urease. Potentiometric method is applied reversible reaction system. But urea hydrolysis reaction may not has a reversible reaction mechanism in electrode surface. Therefore we applied to voltammtricmethod to obtain a sensitivity curve. The sensitivity of sensors was 34 ${\mu}$A/decade.
