本文报道了Nafion/Ni(chitin)_2修饰一氧化氮(NO)微传感器的制作和应用。该传感器对NO具有催化氧化作用,当NO浓度在8.5×10~(-8)～1.5×1O~(-5)mol/L范围内,浓度与峰电流呈线性关系,相关系数为0.9992。该微传感器用于老鼠离体动脉中NO的检测,结果令人满意。
This paper reports the fabrication and application of Nafion / Ni (chitin) _2 modified nitric oxide (NO) sensor. The sensor has a catalytic oxidation effect on NO. When the concentration of NO is within the range of 8.5 × 10 -8 -1.5 × 10 -5 mol / L, the concentration and peak current have a linear relationship with a correlation coefficient of 0.9992. The micro-sensor for the detection of NO in rat isolated arteries, with satisfactory results.
