采用固体技术和酶固定化的方法来制造尿素生物传感元件,并通过测定尿素给出了微型传感元件的某些特性。实验指出,在36℃、pH为7的0.01M磷酸盐缓冲液中,尿素的测定范围是1×10~(-4)～1×10~(-2)g/ml,灵敏度为8～12mV/pk。
Urea biosensors were fabricated using solid-state techniques and immobilized enzymes, and certain properties of the microtensile sensor were determined by measuring urea. It has been experimentally demonstrated that urea has a detection limit of 1 × 10 -4 to 1 × 10 -2 g / ml in 0.01 M phosphate buffer at pH 7 at 36 ° C with a sensitivity of 8 to 12 mV / pk.
